What size tire?
 

What size tires do I need for the proper height on some 17x8 STi BBS's?

Thanks

Get some 18's fool, and then you can be cool.:)

Yeah no help from me, just a bump.

Well 235 40 17 would be pretty close

What about a 225 45 17?

I'm pretty sure I'm running 225 45 17 on mine. 225 50 17 is too big though

225/45 17 RE070 is what comes on them. Stick with that or maybe consider a 245/40/17.

best tire size?
 

The 225/45/17 is real close

225/50-16 Overall Diameter 24.86

225/45/17 Overall Diameter 24.97

225/50-16 Circumference 78.09

225/45/17 Circumference 78.45

With your current 225/50/-16… if your speedometer now reads 65… with the 225/45-17 it will read 65.29

The tire width for both tires sizes is the same… 8.86

:D

I'm with Keith on this selection.

Standard size on the SVX rims would be 225/50/16. Maintaining the rolling radius while growing the rim part means going down 5% per inch. So:

225/50/16 ~ 225/45/17 ~225/40/18

Going to a wider tire at 235 or 245 is seductive I know, but the ride will be wallowy on bends. Handling will be tighter on stock width or even slightly narrower at 215 like the factory did with the '97s.

I'm running 234/45/17 with the STi bbs. With my car having drop springs

Mine will have 245/40/17 General Exclaim UHP's on them.

Try a tire calculator. Stay within 3% of deviance from stock.

I have 18s. They pop Easy. just my 2 cents

Pop easy?
 

Define "Pop easy" please.
Thanks,
Keith

IMO ride quality on 18's is not good.

I have 225/45/17 rubber on my 17's. My 16's look... small on my SVX. I plan to go back to 17's in the near future.
