Max tire size on BBS vert Rims??
 
What's the Max tire width that fit the Stock BBS convertible rims?
Thanks in advance!!

Probably 225's, but go to www.tirerack.com and take the links to the manufacturers info to be sure.

I have 225/50/15's on my other set of vert wheels...Look nice...

Oh..have the set for sale...tires are not that great, but the wheels are good.

Cool thanks, I might try 235 60's to see how they look, if not I'll slap on 225 50's.

235 60's will probably be to tall/wide and rub the front strut. The 225 50's will be your best bet if they don't rub.

These will only be for the rear. But if they do seem to tall then the 225 50's is it. Just trying to fit as much tire as I can for traction

The most tread possible doesn't always mean the best traction. As the tire width surpasses the rim width, the shoulder of the tire will not have complete contact with the ground. While a 225/50 will provide more traction, you'll lose some steering response. 235/60 will definately be too tall and too soft a sidewall not to mention the understeer it's going to encourage.

You should stick with a 225/50 or 215 unless you plan on going to a 7 inch rim or wider.

I run Yokohama AVS dB 225/60/15. I wanted the taller tire, didn't want to go with a 225/50. There aren't any decent 225/55 size tires.

A 235/60/15 WOULD rub without spacers. I can probably slip a business card or maybe a credit card between my spring perches and sidewalls... but not much more. Then DO NOT rub, at all... but they are as close as you could reasonably get and still not rub. Note that the AVS dB and AVS Intermediate are "narrow carcass" tires. Most 225/60 or probably even 225/50 tires would be in danger of serious rubbing issues on the stock BBS rims.

Note that a 225/60 will not have as much trouble with a narrower rim as a 225/50 due to the taller sidewall not having to make as much of an angle...
