345/30ZR19 437s?

Think this would fit after widening the stock 437s to 11.5 or 12"?
Stock offset with 15mm spacers?

That tire would be pinched on a 12Ē wheel. Should be looking at a 13Ē and I donít think thereís enough space within the rear sheetmetal to clear.

Since all the width comes from the inside youíd need more spacer too.

Damn!! I was hoping it would I see the MPSS in the 305/35/19 say the rim range starts at 10" I may be able to push it out an inch and get a wider size on there. Don't want to pay to have the rim modded for a minimal gain though.

May just go with the 305.

Anyone confirm or deny that would fit a stock F82 on stock suspension? Shows .8" taller tire(26.6 vs 27.4) so .4 less wheel gap in the rear..........right?

Why pinch a 305 on a 10Ē? The tire will just bulge over the sidewalls. Instead, run the right size with a stickier compound- lighter, handling will remain crisp, and youíll get even more grip than the MPSS could ever offer.

[assuming you meant 305 instead of 345... if you didnít, holy cow!]
Iíve got Conti 5Ps 295/30ZR19 on BBS CI-R 10.5R on the back of my F80 and they just BARELY fit (but they do fit). 305 was out of stock but the 295s measure almost identical (a quarter inch more narrow). Iíve got no rub or any clearance issues, no spacers or adjustments needed. I drive hard and worked the back end to see if I could get any rub, but allís good.

I don't mind the slight bulge at all, just want the widest look from the rear as possible. Gives me a bit more piece of mind if the wife needs to drive the car. She curbs rims more than anyone I have ever met.

What offset are your BBS 10.5? You mean they barely fit in terms of width I assume. Were they close inside or out?...or both?

Thanks.

This is how a 10.5 ET35 looks for shock and wheel lip clearance.
My suspension is stock so this fit looks like it would easily support a HAS kit.

Cheers and Beers to Tommy L Garage for his custom stone guards (mud flaps). PRICELESS!
If you roll on fatties you need them to keep stone chips and crap off your sides, and they even hold up through carwashes.
