45 or 40 up from on s13 dd?

[s13gebala]

Ive seen alot of racing videos and some of the tire specs were 45 sidewall front and 40 in rear.

the only thing i can think of these helping with is height


anyone have any clues?

im talking about 17 inch rim also

40 to 45 sidewall isn't gonna help you get much height......just get the 40 it will look better

[Matej]

Perhaps they were 17/18 stagger?
Or when there is a large enough difference in width, a 40 sidewall can actually be taller than a 45 sidewall.
For example, a 245/40/17 tire would be taller than a 205/45/17.

or they were staggered in width.

215/45/17 or 225/45/17 Front
235/40/17 or 245/40/17 Rear

right now i have 40/255/17 in the back on a 10 inch.

should i just get the 40?

well you cant really say with out the other specs you're missing, to give you a good answer for what they were doing using those sizes..

...wheel width

...what overall mm width

45 sucks. go with the 40 i hate my 45 series side wall

[Brian]

never run 45s in front.

[nismo 240sx]

40 is more than enough

[Bushido]

I got some 215/45/17's up front on 9.5's

stretch is close to what I have on the back, 225/40/18

ill do 215/40's up front next

[Devil Man]

i have 225/45/17's all around on 9" wheel. its perfect really. i might go 235/40 though for a little more tire hopefully making the tires square with the wheel.

40 is more than enough

Lol, anything above that and you might as well get mud boggers right? :ghey:

[zylvia213]

i would figure they go with 40's in the back for less wall flex if that makes any sense.... idk :hide:
