These tires are beefy!
I really love how big these tires are, great in rain and on dry pavement but not sure about snow and ice yet.

2023 Rubicon - REDDER
SWEET!
Tires went on my baby BLACK Rubicon 2023 paired with candy red rims - it is definitely a high quality tire and also sweet on my eyes! Did not have a chance to test it off-road but is super sturdy on wet pavement.

So far so good!
Great for the multi-terrain use, feels great on the highway, and gets me going on the off road obstacles. Highly recommend it to people like me for the mostly daily, and the occasional off roader

Great tire
Excellent customer support and shipping from ET. Tire is very smooth on the road, virtually no road noise from a 35 12.5x20 with this aggressive of a tread, I was pleasantly surprised. They grip the road well in wet conditions and with winter fast approaching in northern Ohio I’m excited to see what they’ll do !
