"Thunderer LT235/75R 15 Commercial L/T" Unlike others, Simple Tire's website was a breeze to navigate. Shipping est. was 5 days, FedEx dropped in 3 days. Between my coupon, military, Simple Pay Digital Card discounts and free shipping, my savings were unbeatable. Not to mention the great tires: "Thunderer LT235/75R-15 Commercial L/T 10-ply E load range". They replace RV travel trailer tires: ST225/75R-15, 8-ply D load range. Outside diameter for both sizes is appx. 28.3".

All four tires I bought were slightly out-of-round and egg-shaped, causing a vibration between 45mph (accelerating) and 60mph (decel). Had the shop check and confirm they were correctly balanced, which is when they discovered the real issue. Rotating them on my van had no effect, and it didn't go away with time either. The tread seemed to wear faster than I expected as well, but other than those issues they worked as a tire should, although I will add that their off-road performance left much to be desired. Put about 15K miles on them so far, and decided to run them into the ground so I can switch sooner. I will no longer try to save money on tires and will be switching back to USA-made Coopers soon.

Noticed a vibration at 50-60mph after mounting tires, initially thought it was my bad struts. Changed them out, problem persisted. Rebalanced tires, shop said each tire is slightly out of round / egg-shaped. Working on a return/reimbursement process, as there is no excuse for out-of-round tires - I will never buy cheap tires again.

I"ve installed these on a 4500# camper because trailer radials are poor quality and seems like 3 years is what you get out of them before they start to separate. I know the E load range is overkill but has decreased my rolling resistance. these tires balanced well with minimal weights and low road force Have taken 2 1200 mile trips on them so far so good

I don't know about winter yet because it is summer and treadwear is guess because I have only put on 3,000 miles. Overall good heavy tire and did not need a lot of weight to balance.

Good quality, no problems got 6 for my dually and am very happy with performance and traction. Wear well.

Have had them a little over a month. So they have been great.

Last two purchased one was defective (held air roughly 3 days and under 10 miles) but because I own my own tire machine with a lifetime of experience I was not allowed a claim. B.S.!
