I've search around and I can't seem to find a definitive answer. My truck is a 2015 4x4 XLT 5.0 with 17" wheels and I'm curious to know what is the largest tire size that can be fit to the truck. What I have found seems to indicate that around 33" is that max but I wasn't 100% sure. Has anyone else put anything larger on a stock 4x4 without any rubbing issues?

I'd love to put some meatier tires on my truck when the time comes.

On stock with no lift, I believe 33" is correct.

I have 17 wheels also. I think I've seen 275/70/17 mentioned in several threads. Front mud flaps may limit tire size such as those from Weathertech.

If all stock, 34.6" will fit assuming your offset is 44

This is on a 4x4 so has the rear block

would 275/60r20 work stock with the 20 inch wheels?

Fully stock XLT Supercrew 4x4. (not FX4)

I have this size on my '15 Screw with a 2" level and there's plenty of room. Should work stock.
