Hi there. My stock Toyo Proxes need replacing. Will moving up from the stock 195/65/15 to 215/60/15 be okay?

The online calculator says that the speedo will only be 0.7% off...but will they fit on the stock wheel? Any rubbing issues? Thanks guys.

 

If the stock wheels are at least 6.5" wide you should be ok... just enough for a 215, but no more.

 

Thanks for the reply. The stock wheel is a 15 x 6. Do you think it'll fit?

 

Per the TireRack web site, 15x6.5 is the optimal wheel size for 215/60 R15 tires, and 15x6.0 is the mimimum wheel size that will work with those tires.

 

Maybe because of the reduced size of the wheel, or the increase in side-wall height, but I was running 215/50-17" Falkens on my 17x6.5" OE's and I would not have gone bigger on my 6.5" wheels. I would thinka 6" wheel is liable to stretch the tire even more.

 

You hit the nail on the head. The smaller the diameter of the wheel wheel, the narrower it can be and support any given section width of tire. Said another way, while a 18x7.0 is apparently the minimum wheel width for a 215/40 R18 tire, you can get away with a 15x6.0 rim for a 215/50 R15 tire.

 

Thanks for all the help guys! I appreciate it.

 

okay, so is there any benefit in a 215/50/17 vs 215/45/17 ??? what about speedometer?

 

Assumption: Your car came with 205/50 R17 tires with an overall diameter of 25.1"

If you move to a 215/50 R17 tire, your car will theoretically have slightly better grip at the limit, a slight decrease in steering response compared to the OEM rubber, and your speedometer will read a tad low (i.e. you will be traveling faster than it indicates).

If you move to a 215/45 R17 tire, your car will theoretically haveslightly improved grip and steering response compared to the OEM rubber, however, your speedometer will read a tad high (i.e. you will be traveling slower than it indicates).

 

The difference is minimal, but consider also that w/a 215/50 (-12.43 revs/mile) your odometer will indicate fewer miles than the car actually has. W/a 215/45 (+14.8 revs/mile) more miles will indicate. You have to calculate that into a fuel mileage check you do.
The closer to a 205/50 is the 215/50. Less speedo and odo error, but not by much.
I did the 205/50 -> 215/50 plus zero sizing using Falkens and if I had it to do over again, I would go w/the 215/45's.
Just my .02.
