Whats the Lowest Profile Tire I can put on a 20x10 rim>?

[gruvee87vertgt]

I was thinking of a 265/35/20?

You can go as low as 25series sidewall...Not sure why you'd want to though.

You'll need more than a 265 on a 10" rim. I have 275/35 x 20's on my front 9" rims which is about perfect. I also have the 275s on the rear 10.5" rims but it's a bit of a stretch and really needs a 285 or more so I'll probably go with 285/40s on the rear next time unless the Uk starts doing bigger tires.

A 275/35 x 20 is the same rolling radius as the stock 235/55 x 17

so I cant go with a 265/35/20?...has anyone done this?

I'm not saying you can't, any tire will stretch to a degree but it's how it will look on the rim. For example, my front tyre bead sits just about square to the rim but the rear has a splayed gap and the sidewalls curve in to the tread.

Have a look here for all the answers:

This calculator says a 265 will stretch to a 10.5" rim but I wouldn't be happy with that.

This is a 275 tire on a 9" rim and you can see it sits pretty much square to the rim:

I don't really have a good shot of the rears but this one shows the way the 275 has to stretch a litttle to fit a 10.5" rim. Gives it a sort of "drifting" look.

If you take a 1/2" off the width of the wheel and 10mm off the tyre width, you'll get some idea of what it might look like midway between the two.

Oh, I didn't know you were talking about the width of the tire.

Most tire companies recommend 255 as the smallest you can put on a 10" rim. So safely it will fit, but like the above poster mentioned, it probably won't look too good.

I'm running 245/35/20 on the front and 275/30/20 on the rear.

I will be switching the rear to a 315/35/20 though.
