New tires

Erintc29 · July 29, 2018

Hi all! I have a question and I'm pretty ignorant about these things so I apologize if this is a silly question. My truck is a 2015 Sierra with the factory 255 70 r17 tires. My question is what other size tires could go on these same rims without modifying the truck. The tires I like come in 265 70 r17 but I'm not sure if that would work. Thank you so much for your advice!

Im ordering 285/70/17's for one of my sets of wheels tomorrow. It's a 33" tire.. About 11" wide I think. I have a Bilstein level but I don't think it's required. If your truck is stock I bet they fit.

No problem and minimal difference. The figures 255 and 265 are the width of the tires measured in millimeters. The 70 is the % of the height of the sidewall to the width of the tire. Your new tires will be close to 1/2 inch wider and your truck will be close to a 1/4 inch higher off the ground. No need for a step stool! ;-)

May I ask what tire you chose?

Also for anyone else with a close to OEM sized tires, what's a good all terrain tire that has a decent look to it. In other words tires that don't look like they belong on a sedan. I've always like bg Goodrich all terrain but I want a longer lasting tire that's not too crazy.

All terrain tires by design will usually wear faster than a similar quality highway tire. "Looks" is a personal opinion but the best tires for traction, longevity and looks(imo) continue to be Michelin all season tires. (LTX MS/LTX MS2/Defender) I've had them on my past three 1500's and 18 winters without switching to snow tires or using chains.

I’d say bfg ko2s. If you’re wanting less aggressive but still a good, long lasting AT then look at the Yokohama Geolandar AT G015.

I'm going with the Hankook rt03 mt. I think they will look pretty cool on the truck.
