Recommended Tire Size


Drew

Recommended Posts

i would go with either 225/40/17 or 205/55/17

stock diameter is 24.2"

225/40/17 is 24.1"

205/55/17 is 24.3"

these are the closest to your stock tire diameter, so they wont affect your speedometer and odometer.

 

205/40 is 23.5" which is kinda small and will make a noticable difference.

215/35 is 22.9" and that is a lot smaller

drew, it all depends on your area. does santa barbara have nice streets??? if not, dont go for 35's...go a bit thicker with like 40 or 45. how about 215/45/17? those wont bend your wheels that easily...its pretty thick. oh and kumho tires are cheap. i think 17" tires run about 115 or so.. not bad

drew, are the roads in your area good? are there lots of potholes?? if so, get a tire with the middle number as 40 or 45. ie 235/40/17 or 145/45/17. i have 45's and i go over potholes, accidently, and they dont bend my rim. its good to have thick tires if your streets are bad

I think our streets are pretty good, except for a few spots in town. We don't have to deal with harsh winters or super hot summers. It's mild weather year around. And it barely ever rains, except it rained yesterday for the first time in many months. We can go six months without rain sometimes. So the streets aren't that bad.

I'd like to go with a wider tire rather than norrower, and I think 215 is about as wide as I can go without worrying about rubbing too much. So a 215/?/17 would be closest to stock diameter?

 

So I just found this awesome tire size tool. Yeah, I know it say's for Miata's, but it works for all cars. It compares your stock to your new ones and tells you the percentage of speedometer differences as well as the speed difference on the speedo.

Check It and Bookmark It

Looks like 215/45/17 is the closest to stock diameter and only affects the speedo by 1.7%. Although a 225/40/17 is even closer to stock diameter. Wonder if my car can handle a 225. Wow, I could even put 185/30/20's on my car :D

the middle number (eg. 45) is the sidewall height, but it is not the same on all sizes. the number is the percentage of the width of the tire. 215/45/17 equals 215 mm wide 45% of 215 mm sidewall 17" rim diameter. this comes out to a total diameter of 24.6". that will be too tall. i would go with 205/55/17 if you think that 225/40/17 will rub. they are still noticeably wider then stock. and the tire diameter is as close as you can get. i think they will look great your car.

ok, i was just making sure. because the sidewall number is only relative when talking about the width number too. you mentioned 235/40/17 and 145/45/17 as examples. in that example the tire with the 45 woul have a much smalller sidewall. the 235/40 would have a sidwall that's over an inch taller all around, which would make the total tire diameter 2.2" taller then the 145/45.

 

for example 205/40/17 and 235/35/17 are the same diameter. the sidewall is the exact same height. the only difference is that the second one is 3 centimeters wider

oh yeah, your right! i see what your saying now... i forgot about it being relative when comparing with the width...

 

yeah drew, go for 215/45/17s.. kumho tires are cheap... try looking into that but if you have money to play with... go for other brands :)
