Features to know about

Built for Real Highway Miles: Load Range C with 75-mph Speed Rating

When you’re putting on real miles, this setup is ready for it. The Tamarack ST205/75R15 radial tire carries a 6-ply rating and handles up to 1,820 lbs at 50 psi. Its L speed rating gives you confidence up to 75 mph, while the radial design runs cooler and wears more evenly than bias tires. DOT and FMVSS compliance mean it’s built to highway standards from the start.

Balanced Ride Right Out of the Box: Bead-Balanced and Ready to Roll

No extra steps before you tow. This tire-and-wheel assembly comes bead balanced at the factory using internal tire balancing beads, giving it a smooth, steady feel on the road without using external weights. That balance helps extend tread life and keeps vibration down at speed so your trailer tracks straight.

Strong Steel Wheel That Stays Tight: Silver Powder Coat with Beveled Stud Holes

The 15" x 5" steel modular wheel is rated for 2,200 lbs and built to hold torque under load. Beveled stud holes help the wheel seat firmly on the hub so you’re not constantly re-torquing lug nuts. The silver powder coat finish over an e-coat primer resists rust for long-term durability and a clean look that holds up through wet or salty conditions.

Confidence When Conditions Turn: Double Steel Belts and Siped Tread

Tamarack radial construction pairs double steel belts with double nylon plies and a tread-firming overlay that fights separation under stress. The tread design uses open ribs with sipes that channel water away, improving grip when the pavement turns slick or temperatures drop. It’s traction you can feel when weather doesn’t cooperate.

Extra Peace of Mind: 2-Year Roadside Help and No Excuses Guarantee

If a flat happens, complimentary roadside assistance covers you for two years, 24/7 across the U.S., Canada, and Puerto Rico. The tire also carries a 1-Year No Excuses Guarantee—damage it within the first year and it’s replaced at no charge, plus you’re reimbursed a flat labor rate for mounting the new one. That’s real backup when you need it most.

Determining Bolt Pattern

1. Count the lug holes

Look at the wheel hub or the back of the wheel and count how many lug holes there are(also called bolt holes).

Common configurations include: 4-lug, 5-lug, 6-lug and 8 lug

2a. For even lug counts (4-lug, 6-lug, 8-lug)

Measure from the center of one lug hole directly across to the center of the hole opposite it.

Center to Center
Common configurations: 4 on 4", 6 on 5.5", 8 on 6.5"

2b. For odd lug counts (5-lug)

Measure from the center of one lug hole to the outer edge of the hole directly across (not center-to-center since there's no directly opposite hole).

Center to Outside Edge
Common configurations: 5 on 4.5" (most popular), 5 on 5", 5 on 4.75", 5 on 5.5"

Product arrived in a very short amount of time in great condition with no defects. Everything was packaged together without any issues. I will say this might be the best shopping experience that I have ever had from purchase to shipping within 12 hours to arrival within 3 days with free shipping mind you for a 51 lb package. Also a notification letting me know it arrived and to ensure it was in good condition. Impressive, thank you for your services.



by:

Very happy with this spare tire. Looks good, great quality. Shipping was fast, ordering was easy. Good price ...



by:

etrailers web site was extremely easy to use with a lot of information on the product. Fast delivery, boxed well. Would not hesitate to order from etrailer again. Tire is a spare, so no pictures on the trailer.



by:

I have been using etrailer for all my trailer needs as always fast shipping, excellent product and most of all great support.



by:

Ordered on a Friday, arrived that Tuesday. Exactly what I thought I was buying, a brand new fully treaded tire ready to be thrown on the trailer and driven on. Overall, I'm as satisfied in this tire as a person who needed a spare tire could be I suppose.



by:

Perfect match to the tires on my trailer! Evidently, the outfit that built my trailer obtained the tires from etrailer.com. Unfortunately, there was no spare. I was delighted to get a perfect match.



by:

This is an exact match for what I have on my trailer. I will be using as a spare, but when I need new tires I know where to go. From order to delivery was only about 3 days.



by:

Very happy as first tire had wrong wheel size. I called on a Saturday and e trailer helped me get the correct wheel and return the old one expeditious manner. . They understand customer satisfaction. I was more than pleased and would use them again.



by:

I was glad to find these trailer tires and the size that I need. Thank you all very much.



by:

etrailer is the most Efficient company I've ever incounted. I ordered and it shipped the same day. Very detailed who picked and packaged the order and who shipped It. Two days later the tires arrived can't ask for more. As far as the tires and rims they are top quality. Thank you etrailer



by:

by:

Bought this tire in rim for a spear on a cargo trailer.. Paint on rim match the others perfectly overall looks pretty good quality shipping and price with excellent and customer service was fantastic thank you for answering all my questions to make sure I got the right product ...



by:

I can't say enough good things about etrailer. The 15" Silver mod wheels and Castle Rock radial tires made my enclosed motorcycle trailer pop. The pair even arrived earlier than expected. This was my second purchase and I"ll be back again in the future.

Great, exact match to tire and rim on trailer



by:

From first impressions the product seems to fit my needs for a spare tire on my enclosed trailer perfectly. Quality of the paint on the rim is very good and tire specs are spot on. That’s why I continue to use etrailer as my go to provider for this type of product.



by:

Replaced old rusty factory spoked wheels and weather checked tires. The wheels and tires are great. Only complaint is 1 of the wheels paint flaked off in big pieces not a big deal.



by:

Well, I bought the tires and rims as spares in the event of primary failures. Fortunately I have not had to fall on those reserves but, with that my purchases there of have been holding up and held up well with the mounts and gear from etrailer.



by:

My order came in on time, as promised.Very easy to navigate the website and order the tire I needed.

Great spare tire pricing was very fair.



by:

Purchased a spare tire to go with the etrailer spare tire mount for my angle iron trailer. Purchased for security should a tire fail. Wanted to keep the tires and spares the same for aesthetics. Wheel is without any scratches, inflated and ready to go! Thank you etrailer. Tire was out of stock at the time of purchase. I was contacted about an in stock option. I opted out to get the same combo I have but I appreciated the offer. Only took two weeks anyhow.



by:

Tire & rim are exact replacement for my trailer. Shipping was quick even though you had addressed it to the incorrect recipient.

Thankfully I havent had to use it!But I know if I do itll fit.



by:

A lot of new trailers today don't come with a spare tire mine didn't this product was an exact match and fit and it came ready to go I recommend this product if you're in the same situation



by:

Acceptable price and quality looks great! Quick turnaround from placing order to arrival of product. We had a blowout heading to our latest camping trip and nobody in the area had a replacement. The quick turnaround from the etrailer team was greatly appreciated because we had to have the spare before heading back home.



by:

Great company!
Just bought a 2009 Forest
River Wildwood Travel Trailer.
Locating, ordering and delivery of your tire was never faster or more efficient!
I know this sounds like a solicited review, but I assure you, it’s legit.
I will definitely use this site, again
Thank you, kindly

  • What is The Difference On The Wheels With Wheel and Tire Packages # LHACK121 & # MX57FR?
    The Silver Modular Trailer Wheel # LHHA315 from the Castle Rock ST205/75R15 Radial Trailer Tire w/ 15" Silver Mod Wheel # LHACK121 has a powder coat finish. While the Vesper wheel on the Provider ST205/75R15 Radial Trailer Tire w/ 15" Vesper Silver Mod Wheel # MX57FR has an acrylic enamel finish which is more durable than powder coat. Each manufacturer is going to have their own specific paint codes they use but the Wheel and Tire # LHACK121 you found does appear to have the darker finish....

  • Comparing Spoke and Mod Trailer Wheels
    Mod wheels such as the one in tire and wheel combo # LHACK121 have the distinctive round holes. A "regular" trailer wheel on the other hand has more triangle shaped holes and is referred to as a "spoke" wheel. Take a look at # LHAW124 as an example. So basically you are looking at an appearance difference. I have included links to video reviews of both for you.

  • Recommended Replacement Tire for a 2020 Riverside Retro 190BH Trailer
    From what I could find out, your 2020 Riverside Retro 190BH weighs right at 4,000 pounds, so it looks like you may need a tire with a D weight rating. The Westlake ST205/75R75 Radial Tire # LHWL300 will have this D weight rating, or 2,150 pounds at 65 psi, and will be a better match for your trailer. This is also a radial tire, making it good for highway use, and has an L speed rating, which is up to 75 miles per hour.

  • Spare Wheel/Tire and Mount for a 2020 Coleman Lantern LT 274BH
    In order to choose the correct spare wheel/tire for a 2020 Coleman Lantern LT 274BH we first need to know the tire size and load range. The tire size is listed on the sidewall of the tire along with the load range which should be LRC for load range c or LRD for load range d. I see you were looking at 205/75-15 tires so if that is what you have then the Castle Rock ST205/75R15 Radial Trailer Tire w/ 15" Silver Mod Wheel part # LHACK121 is what I would use if you have load range c tires or...

  • Correct Wheel/Tire Size for Cargo Pro Trailer
    I don't have any sure fire way to know what size tires or bolt pattern a Cargo Pro Trailer uses nor do I think they all use the same size but in order to confirm you simply need to count the number wheel bolts and look for the listed size on the sidewall of the existing tire. There should be a load range rating as well which will be needed to confirm an exact fit. The Castle Rock ST205/75R15 Radial Trailer Tire w/ 15" Silver Mod Wheel - 5 on 4-1/2 - Load Range C Item # LHACK121 uses five...

  • Does the Castle Rock ST205/75R15 Tire with Wheel Come Balanced?
    The Castle Rock ST205/75R15 Radial Trailer Tire w/ 15" Silver Mod Wheel - 5 on 4-1/2 - LR C # LHACK121 does come ready to install and go down the road. It comes as balanced as trailer tires need to be from the manufacturer (trailer tires don't use weights like vehicle tires for balancing).

  • Can Radial And Bias Ply Tires Be Mixed On A Trailer?
    It is not recommended to mix bias ply and radial tires, so you would not want to use the Loadstar ST205/75D15 Bias Trailer Tire w/ 15" White Spoke Wheel - 5 on 4-1/2 - Load Range C # AM3S640DX to replace a flat ST205/75R15 tire. Bias ply and radial tires track and perform differently which can cause an unstable ride, and can wear tires quicker. I recommend going with the Castle Rock ST205/75R15 Radial Trailer Tire w/ 15" Silver Mod Wheel - 5 on 4-1/2 - Load Range C # LHACK121 which has...

  • Picking Out Spare Wheel and Tire for Trailer Tire Size 205/75-15
    Nearly all 5 lug bolt patterns for trailer wheels use the 5 on 4-1/2 inch bolt pattern. I'd be willing to bet that's what you have as it's so popular. For that the Castle Rock Wheel and Tire part # LHACK121 is a really great option for a spare to have. It's priced great, has a higher speed rating, is a radial, and has a warranty that includes roadside assistance. I attached a link to a review video for this wheel and tire as well as a link to a page that has all the wheel/tire combos we...

  • Spare Wheel and Tire Recommendation for Trailer with 205/75-15 Wheel and Tire
    Thanks for the picture of your wheel and tire! From that I can tell you need a 205/75-15 tire with a 5 on 4-1/2 inch bolt pattern. For a wheel and tire that will work great as a spare we have the Castle Rock ST205/75R15 Radial Trailer Tire w/ 15" Silver Mod Wheel - 5 on 4-1/2 - Load Range C # LHACK121 which has the same size tire and bolt pattern as well as has the same mod wheel design.
