I switched from Maxxis to goodyear endurance. cost was basically the same, endurance is a real >65mph speed rated trailer tire (85mph IIRC) without any load reduction based on speed. AFAIK Maxxis is still an excellent , but in my mind no longer the top of the heap,

I was looking on Maxxis’ website before I posted this and wanted to see if their “plus” designation was for speed rating. Saw nothing referring to speed ratings or de-rating weight for speed. I may need to send them an email and ask…

I am prepping for our big 3000 mile round trip this summer and want to get rid of the stock tires on our 2021 KZ Connect. I have used Maxxis M8008 tires in the past and they USED to be THE tire that was considered the best. I’m just wondering if they are still the best or a really good tire at the very least.

I've had both. Next time I'll be going back to Maxxis only because Endurance doesn't have enough tread depth to last long enough for me.

Hi Haulin,

I looked up your camper, this one correct? https://www.kz-rv.com/2021-products/conn........t-se-travel-trailers/2021-C312BHKSE.html

What I was looking for was the GVWR and the tire size. It lists a 9,460 GVWR and 15" tires, but does not state a load range. I'm going on the assumption you "might" have ST225/75R15 load range D? I'm hoping they did not set you up on ST205/75R15 Load range D which is a smaller tire in diameter and weight capacity. If you are on the ST205's we really need to talk about this.

Getting the right tire weight rating is as important for long-lasting as the tire brand. Those of us with 10,000# GVWR campers fall into this issue as interply shear wants to play havoc on tandem or triple axle trailers tearing the tire apart in turns. The only way to help gain more safety factor to ward off the interplay shear, is to get more reserve tire capacity above the heaviest loaded wheel. I was recommended to get at least 20% more reserve capacity above the heaviest loaded wheel as the target to help ward off the interplay shear effect.

I had 3 of my ST tires fail from this issue and was on the ST225/75R15 LR D's. I did not have the 20% extra, but I had all the weight slips and was under the tire weight rating. In this case, to get out of the problem, you up a load range to E's if you are staying with 15" ST trailer tires, or you change wheels to 16" and go to LT225/75R16 LR E. In my case, I spent the money to go with the 16" LTs and deal with the wheel well clearance issues on the 10K loaded camper in my sig.

Now on the brands, there are only three brands I would recommend from my experience.

The Endurance only makes ST's in the E load range on the ST225/75R15s; they do not offer the D's, hmmm maybe GY knows something about this!

The Maxxis, I have had good luck with them, other than the heavy weather checking in the treads and sidewalls at the 5-year mark. By then, the tire needs to be changed anyway. They do offer D and E, again getting the right size with enough reserve capacity.

The Carlisle Radial Trail HD, these, and only this tire from them for a travel trailer that tows long distance, heavy. https://www.carlislebrandtires.com/our-products/product-detail/radial-trail-hd/

Carlisle used to have a big issue with ST trailer tires, but when they redesigned them to this Radial Trail HD, they corrected their issues just like GY did with the Endruance over the Marathons. I used these on my flatbed trailers and project campers. Again, get the right weight rating with the needed reserve capacity.

Hope this helps

John
