Im currently looking for snow tires and came across some but the size is slightly off. The tires that I have now are 225/40 rz18. the tires I found for sale are 225/45 r18. Will these tires still fit?

 

oem size for rx-8 is 225/45-18 or 225/40-19 why you have 225/40-18 is beyond me

 

I just bought this car and these are the exact tires on it, Continental extreme contact dw 245/40 rz18. Anyhow, thanks for the info.

 

Looks like you made a typo. Care to specify which size you have?

Like speedracer said, stock size is 225/45R18. Another common option is 245/40R18 as they are very similar in daimeter, yet 20 mm wider.

I would suggest narrower tires for winter use though, as they perform better through snow and ice. Do you plan on mounting them on stock wheels?

 

So 245/40R18 would go on stock 8J 18" wheels then? Blimey, I look at my alloys and the tyre is already out from the alloy?

 

18x8 wheels are within the suggested range for 245/40R18, but it is on the edge.

 

Yes I plan on mounting them on stock wheels. Thanks for the info.

 

There are many type of companies for tire and wheels.Bridge stone, Yokohama, piccalilli these companies are famous for tires and wheel.

 

Hi all,Every one confused about tire and wheels and i think Bridge stone and Yokohama these two companies are famous for tire and wheels and (all type of tire)are good for tire and wheel.

 

 

215-50-17 on cheap 7.5" wheels works well for snow tires .....

 

Why not? I bought a barely used set of Blizzaks in that size for $75 a piece instead of the retail of $281 a piece. So the speedo is off a bit. Who cares?

 

 

Will 225/45 fit a 18x9 wheel?

 

Yup, will be a tad stretched though.

 

This thread is a fail. Not really sure whats being asked... All the sizes mentioned so far will fit the stock wheels. and under the car.
