Your opinion on tires.

205/50/15 in front and 225/50/15 in the back. The tires are Hankook Ventus R-s2 here is the link

I love them and they handle great. Chris

Those Hankooks look nice and thyanx for the chart 240ZMan.

You guys know those tire size caculator sites that says "(X) amount of

tire diameter above 3% original size risks brake failure"?

Is there any truth to that?

I'v been using this site here which seems to be pretty good I guess.

Hmmm, I haven't seen the 3% warning before. I can imagine a few reasons to be concerned, but none seem likely enough to put a big warning up.

From my days selling tires, I recall that there were several issues around the 3% figure. Most had to do with varying local regulations, and load capacity safety buffers.

But the brake warning (as I recall) had to do with modern cars with anti-lock brakes. Which is most anything these days. I seem to recall that some ABS controllers get fatally confused if the diameters of the tires are not all similar. After all, ABS works by comparing the relative rotation speed of all the tires. Not a problem as long as all the tires are the same size, even outside the 3% window. But most people don't change their spare to match. So if you have a flat on one of these ABS equipped cars and your spare tire is not within 3% of the rest of the tires, ABS problems can arise.

And ABS problems can be expen$ive! Which is probably the reason for the warning. "We told you not to do that!"

This is the chart I use. I like it because it shows you the tires in pictures so you can see a visual comparison.

That websites tight!

I can use that to find all sorts of rims and see if the offset

will clear the backspacing ahead of time !!

Great Find MARS :rambo:

Yeah, go figure though.

Mordern day stuff is the reason why my favorite rim company,Tenzo,

don't make any style for Z cars cause of that front wheel drive

offset crap.

Dang postive offset :mad:., +22, whats that about

It's about engineering. Even a majority of the few RWD cars made today use positive offset. My BMW has 17x8 +38 on it...

I had yokos 205 55 16 it was a hard ride and the tires wore down too fast.

[mars23z]

Yeah I use that site all the time. It has saved me money more then once
