This Tamarack ST205/75R15 radial tire and black Margay aluminum wheel combo is designed to run long and smooth at highway speeds. The Load Range C tire has a 6-ply rating and carries up to 1,820 lbs at 50 psi. With its 81-mph (speed rating M) capability and DOT-compliant construction, it’s a solid match for long hauls or frequent highway travel where steady heat resistance and tread life really matter.
This assembly comes balanced using internal tire balancing beads that smooth out the ride without external weights. That means less vibration, longer tread life, and a more stable feel through varying road conditions. It’s a smart setup for anyone who wants to bolt on a combo that’s already tuned for even wear and consistent handling.
The 15" x 5" aluminum wheel is built tough yet stays light, resisting corrosion season after season. Its Margay Series 5-spoke design in black with an automotive-grade clear coat keeps it looking sharp while protecting against scuffs and scratches. Rated at 2,150 lbs, it pairs strength with style in a wheel that won’t rust like steel in wet or salty environments.
Tamarack backs this setup with two years of complimentary roadside assistance available 24/7 anywhere in the United States, Canada, or Puerto Rico. The tire also carries a 1-Year No Excuses Guarantee—if it’s damaged in any way not covered by warranty during the first year, it’s replaced at no charge along with compensation for mounting labor. That kind of support adds peace of mind every time you roll out.
Inside, the Tamarack radial tire uses double steel belts and double polyester cords wrapped in protective nylon to help prevent tread separation. The sturdy sidewalls handle heavy loads while maintaining flexibility for smoother highway travel. Combined with siped tread channels that move water away on wet or icy roads, it’s built to keep traction steady and wear even mile after mile.

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.
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).
Common configurations: 5 on 4.5" (most popular), 5 on 5", 5 on 4.75", 5 on 5.5"

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.
