33x12.5r20???? Help

[Chisam117]

Can I run 33x12.50r20s on my stock 20x8.5" rims with a 2.25" leveling kit on my 08 silverado??

I put a 2.5" kit on mine and have cooper stt 33x12.50r20's going on today hopefully. I can let you know that goes. I saw a lot of people running the nitto trail grapplers 295/55r20's and they measure out to a 32.91 x 12.52. Hope that helps and I'll post how mine goes.

Awesome. I'd appreciate it if you mind I'd just hate to spend all that money on tires and it really not work lol

They are going to rub quite a bit, so be prepared to cut.

Hey blackout jus driving normal are they gonna rub like a boss or jus when I'm in a bind turning hard uphill or something like that?

[blackout07]

In my experience they will rub badly under normal driving. Although some claim to have no rubbing at all, which I find to be improbable. I tried it with just a leveling kit while I was waiting for my body lift and it wasn't happening without cutting metal. They still rubbed in off camber situations with the addition of a 3" body lift. The wheels were aftermarket, 20x8.5 with a +18 offset...essentially stock specs.

[Chisam117]

I see. Well the wheels I'm wanting are only available with a +35 mm offset I guess going from a + 18 to + 35 won't make that much difference will it?

It will help in a way. It will ease the amount of rubbing on the fender, but increase any rubbing on the sway bar since the tires will be pulled in more.

[Chisam117]

Ok man I appreciate the help. I guess I need to look at some different tire sizes then.

[blackout07]

It can be done with trimming.

Update from my tires. Turned the wheels to full lock after putting on and don't see any rub. No extra noises going down the road and nothing shinny under there once I drove it home. Turned the wheels to full lock again after getting it home and don't see it touching anything. So I'm going to say no rub on the flat. I don't know if you were ever angled for some reason it would rub but I would say under normal driving I'm not going to have any problem. Don't get me wrong its tight in there now but its not touching. Will try and get some pics up soon.

Alright sweet. I was looking at mine yesterday with the wheels turned and it looked like it will be pretty snug but also I haven't put my leveling kit on yet Im jus waiting till I get my tires to put it on. I'm sure there might be times it'll rub but for jus driving normal sounds like Ill be good. Thanks for the update I was anxious to hear how they did. Is your truck the newer body style though? If that would a difference or not

[sierra2007]

That's my wheels turned the whole way. I have a couple other shots in my gallery. I wouldn't think the .25" difference between you kit and mine would make a whole lot of difference.

[Chisam117]

That's what I was wanting to see man. Thanks a lot! Truck looks real slick with those tires. Yea I'd agree I don't think that a quarter of an inch will matter at all

No problem I too did a lot of searching and reading before I purchased my tires and was still nervous that they would rub but now that they are on I love them. I'll tell you I went with the coopers for 2 reasons a) I previously had them on my stock 17's stock size and liked them b) On their website they measure them at 32.66x12.49 which I felt would comfortably fit.
