Spare tire options

So you guys running 17 inch wheels and larger, What are the options for spare storage? I'm running 17's and I don't think the 50 series is going to fit that well into the tire storage, I've been wrong B4, lol.

The outer diameter of most 17 inch wheel and tire combos for our cars are the same or nearly the same as the factory wheels. So there is no real reason not to use the factory spare tire. The only time you would need to have a different size spare wheel is if you have larger brakes or something that would prevent using the factory wheel and tire.

OEM tire size was 225/65/15.  I run 235/70/15 (more options for tires these days) and it's a tight fit in the spare tire well.  The limiting dimension might be the sidewall width rather than the tire height, which is only a fraction of an inch taller on a 235/7015 vs a 225/65/15 (27.95 vs 27.40 inches).  If the tire is too fat through the sidewall dimension, it might be a tight squeeze unless deflated.

A 215-60-17 is 0.10 inches in diameter larger than a 255-50-17. It would make a good spare if you have trouble getting a 255 in the spare well.

Some of the RM wagons came with 235-70-15s, so they should also fit in the well, but are tight.

Depending on the rim width, the sidewall is the determining factor. A narrower rim will make pinch sidewall to some extent.

I have the stock size 225/75/15 in my spare area, it seems to fit no problem. I'm running 255s also, but wouldn't keep the spare on obviously, so I don't mind it being off from the other four tires and rims.

The only issue you might have is if you have a limited slip differential. It would make it "work" until you got the other tire fixed/replaced.
