i am planning to buy a set of winter tires for my stock rims. apparently 225/45/18 is the size of stock tires. my question is:

is 225/45/18 the ONLY tire that will fit my stock rims? i don't plan to change the rims. thanks

 

no, i ran 245/40 on my stockers for years. i'm not sure how much skinnier you can go though.

 

no.

 

you can fit different sized tires on the OEM wheel, just as 2tone mentioned. 245/40 is what I ran as well on my OEM wheels.

shallowater: where are you located?
maybe membes in your area can help with picking out a good winter tire (and size)

 

What's your location? I have 2 almost new winter tires for sale.

 

thanks all for the answers...anywhere i can find a list of compatible tires?

i am near Boston, Metrowest area.

I see you are in FL, why would you have winter tires in the first place? :-)

 

Goggle...?

 

Because I just moved down from NY. Here is my for sale thread...they are still
in NY at my moms.

how about you offer some advice instead?
if you google, "mazda rx8 what size tire oem wheel" you really get nothing of use.

 

The 245/40 would be a little cheaper because they are original equipment on 'Vettes etc, but you don't want a fatter tire for winter, you will skid/slide/aquaplane/spin out more.

I bought cheapo alloys and went 17", it was cheaper in the end than buying 18" snows......

My local tire place charges $120 to change and balance - that's $240 a year wasted if you swap every fall/spring. This is my sixth winter, so the alloys have MORE than paid for themselves, plus I don't have to wait for Mr. Tire to 'fit-me-in'.
