Like the title says. The wife's Avalanche is due for tires. Can anyone tell me if 285's will fit with any problems.

Edited to add: Stock '03 Z71. Thanks

I have saw them on them so I'm sure you can get them in there..

I would search the Avalanche forums out there for ant issues.

They fit on my dad's '02 K1500 Suburban just fine, so I'd assume they would fit on the Avalanche.

Is it a 2500 or a 1500? Is it the 5.3L or the 8.1L? And, what gear ratio do you have in the back?

If you have the 8.1 or 4.10 gears I think you'll ok.

Sorry it took so long to get back here. The truck is a 1500 Z71 5.3 with 4:10s.

I think with 4.10's you'll be OK, but your mileage is gonna suffer a bit with the bigger (wider) tires.

I just traded a 03 z71 avalanche for a H3 Hummer. My avalanche came stock with a 373 rear end. 265 were the largest tire i could get on it stock. I actually put a fab tech 6 inch lift on it with 305 tires. Also put a hypertech on it and it performed decent with that set up but it sure ruined the ride and handling. Gas mileage was about 13 with that set up.

Thanks guys. I'll probably just put the 265s back on it. Thinking about the Bridgestone Dueler Revos. Anyone have these on an Avalanche?

I had some 285 Wrangler AT/S's on my 2000 1500 and they looked awesome, but they made the truck shimmy at highway speeds and I tried to have it balanced several times. Even with the 5.3 and 4.10's there was a noticeable power loss going up to the 285's. If you just want them for looks they'd probably be just fine but I feel the ride will be comprimised. If you're towing anything I'd stick with the 265's. You wouldn't think there would be that much difference between the 265's and 285's but trust me there is.
