The tire manufactures seem split on whether 10.5" or 11" is max rim width for 285 - 30's.

I'm not worried about clearance / rubbing issues, more interested in sidewall angle / contact patch usability.

Of course, ensuring the beads stay seated would also be nice.


Thanks

It's not an issue at all.... I have 285/30's on my Ruf modulars.

I run them on my 996 turbo rims. Asked a couple of well respected tire & racing folks and they said the 285's would be fine on the 11 inch rims. But I am planning to switch to 295's when the 285's wear out... they just look a little odd on there.

no problem...run the hankooks on my bbs lm's...actually gives it a nice rounded track look

285 is max for 10.5. i think 11 you an go all the way to 305?

PNogC2S

Actually, I've been told you can go all the way to a 315 on an 11 inch. But back to the question at hand. Here are a few pics that may help answer =1000 words and all that...
Note: these are PS2's with the rib that makes them look even more stretched.

Thanks for the feedback guys.
PNog, is it safe to say that the no part of your tire's sidewall extends past the inner or outer flange of the wheel?
i.e.; if you were to lay two wheels on top of one another, you would have metal to metal contact, not rubber to rubber?

thanks

tjangi, your friend in the avatar seems to have a great sense of humor!

285/30/18 PS2 tires on my 11" Carrera III rear wheels. You can stack the wheels on top of each other with no metal-to-metal contact. All rubber.

It really depends on which brand and model of tire you are trying to use. Bridgestone RE050A tend to run very wide for their size while most Continental tires are on the narrow side.

If you stacked them there would not be any metal to metal contact, but as mentioned earlier, the michelin ps2's have a rib on the sidewall -- I think it's there to protect the rims a little...can't think of any other reason for it. So anyway, that rib sticks out past the metal of the rim...not sure if another brand would be same/different.
