I really need to get my eyes checked. I thought it was 20x12 lol. So for the 305/40/22 max rim width is 12.0. For the 305/45/22 max rim width is 11.5

So you think I'm good running 305/45s on my 12 wides? I'd like the 45 over the 40 since it's basically a 33" tire

What's your opinion on temporarily going over a tires speed rating at the track? I'd like to stay with what I have but if going over what they are rated for even if it's only briefly is unsafe then I'd like to address it that's the whole reason of this thread

I believe the speed rating is for one hour of constant speed. I wouldn't be too worried at the track.

I'm glad you guys have your opinions on my truck. But I don't really care honestly. I like the way it looks. If y'all don't. Sorry! But when I've got guys around here poking the same size tire out on 14 wides, no i don't really see any issue ESPECIALLY given there are thousands of guys out there doing the exact same thing and not having issues. Even trucks going down the strip at rudys had 12 wides with the same size tire. Heck. One Cummins had 24x12s with 305/35s. If a truck can do a boosted 4 wheel launch and fly down the drag strip multiple times in the course of a few hours with this setup, I have absolutely no problem with my setup

I have 305/40s on my 22x11s and the sidewalls sit perfectly straight up. There is no stretch or bulge. You might get a tiny bit of stretch on a 12 wide but it shouldn't be terrible. There are 0 offset though so obviously a 12" -44 will stick out a lot more.

Now you just went full potato. If your tire is 12 inches wide and you use a 14 inch wide rim. That's not okay. It's not calculus. But thousands of people do it so it's fine. Thousands of people **** their cousin, still don't mean it's right.

horrible off set, wide wheels on tires too skinny and then want to use them at the track......

next post will be "how can i get my 60 ft times down, i cant go below a 1.8-1.7 without the steering wheel trying to rip out of my hand"

the STT Pro speed rating wont be any more of a worry that stretching those tires on 12" rims

These tires have a low weight rating as it is. I don't see how stretching them can seem like a good idea.

Get civic and "stance" the **** out of it

Never said these tires on a 14 was ok. I said people do it. I don't know what huge bulge you see on my wheels but there isn't one. Are they stretched? Yeah. They are. Do I care? No. Do I tow? No. The load rating is 2600lbs a piece. The approved rim with rating goes up to 12 so according to the manufacture I'm perfectly fine with my set up. I like my truck how it is. And to the OP if you want to do it then do it. You've seen how it looks and it's your truck. Same difference as these guys putting 650+ hp on a stock bottom end. Should you? No. But some do. And if people hate the idea or don't like it then who the hell cares. They don't have to do it. Factory wheels are 7 wide and guys put 315/75s in them. They state the rim range is 8-10. Same difference to me. I did it. I'm sorry. But it's my truck.

What am I missing. According to nitto you can run the 305/40/22 on a 12 wide rim. So nitto is okay with the tire being stretched?

I run 8 wides on a 305/50 with a +12 because I'm not a douchebag, nobody out there can say they running a 12 or 14 wide saying it's for performance, I cut a consistent 1.7.
Wide wheels, huge negative offset, and stretched tires is by far the gayest trend I've ever seen, so many good looking trucks out there with fcking ugly ass wheels.
