Features to know about

Made for Long Hauls at Real Highway Speeds: Load Range D with 81-mph Speed Rating

This Tamarack ST225/75R15 radial tire and aluminum wheel combo is built for serious miles. The tire’s 8-ply rating supports up to 2,540 lbs at 65 psi, and the M speed rating (81 mph) means it stays stable and cool on extended highway runs. It meets DOT and FMVSS specs for dependable performance when you’re towing at speed.

Smooth, Balanced Ride Without the Guesswork: Bead-Balanced Assembly

This setup is ready to roll right out of the box. The tire and wheel come bead balanced using internal tire balancing beads, so you don’t need external weights. That balance translates into a smoother ride and helps extend tread life over time. The result is less vibration and more confidence mile after mile.

Built to Handle the Elements: Black Eagle Aluminum Wheel with Steel Lug Nut Inserts

Corrosion doesn’t stand a chance here. The lightweight aluminum wheel resists rust, while its automotive-grade clear coat finish protects against scuffs and scratches. Pressed-in steel inserts inside the lug nut wells prevent wear in high-stress areas, keeping the wheel securely attached without constant retightening.

Reliable Grip in Wet or Icy Conditions: Siped Tread for Better Traction

The Tamarack tread design uses ribs with breaks and fine sipes that channel water away from the contact patch. This helps maintain traction when roads are wet, snowy, or icy. Double steel belts and double nylon plies reinforce the tread for strength, while nylon overlays help prevent separation under heavy loads or heat buildup.

Extra Protection When You Need It: Roadside Assistance and No Excuses Guarantee

Every assembly includes complimentary roadside assistance for 2 years across the U.S., Canada, and Puerto Rico—24/7 coverage if you get a flat. The tire also carries a 1-Year No Excuses Guarantee and a 5-Year warranty, with added labor reimbursement if replacement is needed within the first year.

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"

Video Transcript for Trailer Tires Explained by the Manufacturer Lionshead Tires

Hello neighbors, it's Brad here from etrailer, and today I'm at N.A.T.M. And this convention brings a lot of the vendors that we have at etrailer to a convention where we have their booths and their products set up. I had a chance to catch up with quite a few of them. So let's take a look at their products a little bit up close in, ask some of the questions to those vendors about their products. I'm here with Tim from Lionshead. And Tim, what is Lionshead Lionshead is a privately held tire and wheel distributor.

We actually have seven locations nationwide, and we sell about 2 million assemblies a year. So you guys have been in specifically trailer applications for 30 years Tim Yep, absolutely. So not only do you have the years to prove that you guys are, you know, one of the best out there, but also having OEMs with your tires on them in place shows that if, you know, they're building these trailers, they want great tires for the customers, but you guys are the ones to provide that. Yeah, yeah. Thank you, yeah.

We focus just primarily on OEMs, and you're right, they're looking for a very set criteria of specification, quality of tire, and we're happy to provide that. So what offerings do you guys have as far as at etrailer Sure, so at the brands, the tire brands that we're fortunate enough to provide to you guys include the fact that we're direct with Goodyear. So the Goodyear Endurance would be one of the brands, as well as our WestLake Tire, and then our Tamarack private label brand. And where do those fall into Is it like a tier system It is, it is. So our private label would be good, WestLake would be better, and obviously with Goodyear being Tier 1 branded product, that's your best tire.

So if someone has their, you know, tires kind of maybe potentially wearing out, what are things that they can look for, and, you know, how do they get the right tire size They wanna treat it just like their passenger car tires. That is, you're gonna wanna look at tread depth, you're going to want to inspect for any sort of damage into that sidewall and any sort of irregular tread wear. If you see any of those criteria, you're gonna want to take it to a dealer or a retail location, or you're gonna wanna take and look at etrailer and find your replacement tire or your replacement assembly. So a replacement assembly. So that's tire already mounted up on a wheel, you can literally just bolt it up and be ready to go.

Why would someone go with that over just a standard tire Yeah, for that straightforward convenience. A lot of times, if a tire is damaged or has an issue, oftentimes that wheel is aged and can have some issues, making it a little bit more difficult to remount. So if you buy the whole assembly, it's literally just taking off the lug nuts, putting the new assembly on and, you know, retorquing the lug nuts. No having to run to a tire shop with your wheel to get it all mounted, yep. No added cost to that, too. Once you have that, you're ready to go. Yep, absolutely. Now, okay, if I have tandem axle, triple axle, and I have a tire that I'm replacing, should I go and do, you know, replace all of them Right, so each individual experience is gonna be a little bit different. No different than a consumer that's buying a car. Some will just replace the subject tire, or other owners are gonna replace all tires at the same time with the belief that if this tire's been subjected to the same conditions, do we just take this one opportunity to replace all We always recommend that you replace all because of that criteria. That makes perfect sense. And as far as maintaining your tires, I mean correct tire pressure's probably number one, I would assume. Do you need to rotate tires Right. So the the key attributes, what you're gonna wanna stay focused on is proper PSI and make sure you don't overload that tire station. Both of those criteria can really lead to shortening that tire's useful life. As far as rotating tires, not really needed because it's in a tow application. It's not as if the front tires are subject to any different kind of wear pattern than the, you know, other stations. That makes sense, yeah, there's nothing driving or spinning it any more than the other one, so, yeah, absolutely. Well, that's good tips 'cause I get a lot of questions from people with campers that ask those questions, and I am not exactly sure I knew, but now I do. So huge thanks to Tim from Lionshead for taking the time to explain what Lionshead offers. That way, you can get tires back on your trailer and back on the road. Great, thanks so much. I appreciate it. Thank you.

  • Is The Black Eagle Aluminum Wheel CR99ZR A Matte Black Wheel?
    Hey Liz, thanks for reaching out. Yes, the Tamarack ST225/75R15 Trailer Tire with Black Eagle Aluminum Wheel # CR99ZR is a matte black aluminum wheel. It's the same matte black coating as the # WST69FR wheels you've ordered previously. It has a low-gloss appearance rather than a shiny or gloss black finish, making it a great match if you're going for a blackout look on your trailer. What trailer are they going on?

  • Spare Tire And Wheel For Winnebago Thrive 25RLS Travel Trailer With ST225/75R15 Maxxis Tires
    Hey Timothy, thanks for reaching out. We do have ST225/75R15 tires you can use for a spare for your Winnebago travel trailer. I don't have a way to look up the exact wheel type using the VIN, but looking at pictures of the Thrive 25RLS online, it appears they have a black aluminum spoke wheel. So, I'm not sure if what we have will be an exact OEM match, but I will list some similar options for you below. I'll also need you to confirm if your wheels are a 5 or 6 lug.
