295/70 - YES they fit! :)

Frankf300 · February 6, 2016

I wanted to help people out who are looking for tire options. I searched forums, asked questions, the whole 9. But not many people are running 295/70R18 on these new trucks(at least not on the forums). So I really was only able to go by a couple guys and my own measurements. Well I took the gamble today it worked out great! I researched for a while what the smallest diameter tire in a 295/70 would be but while still keeping the aggressiveness I wanted. I went with the Cooper S/T Maxx. The sidewall actually says 34x11.5. My truck only has a 2" RC level. The guys in the tire shop mounted one up for me first and we checked for rubbing. I'm not rubbing any components at full lock (sway bar, UCA). I get very very slight rub on the inner carpeted liner. It's so little I will probably not even tie back. I wouldn't be surprised if there was a little more rubbing with an M/T tread like a Trail Grappler or STT Pro since the overall diameter is a little larger.

So to sum up: 2015 Sierra Z71 with a 2" RC on stock z71 18" wheels - 295/70 DO fit nicely with very MINIMAL rubbing on carpeted liner (seems to be full lock in reverse).

Pictures to follow shortly!

Great to know Frank!! And thanks for the pics....tires look really good!! I've had the ATP's now for about 18k miles with zero issues. Will try the S/T maxx's next for sure.

Nice!

I like my ATP as well. I'm thinking about the STT Pro next time.

I've had A/T3's on 2 previous trucks and we run them on our work van and I've always loved them. Had Coopers on my wife's old car and was again very impressed. Of course I am paying the price on the "growl" factor down the road with these, but I expected that with this tread. They definitely make some noise when you're barreling down the road lol. But I wanted more aggressive so I knew what I was in for. Obviously I'll have to see when the miles start racking up how they hold up and keep up with my tire rotations.
