Ok i am thinking of running 18x9 all around. What do all of you think? and what tire size should i have? Thanks

 

should be good, my rear 18x9s fit fine in front, just can't use the stock 225s with them.

 

2003z, soi what size tires do you use for the front and rear?

 

Check on Tirerack.com for tire sizes for the 9" rims. You will probably find a tire that will be about the same diameter as the stock tires. Look at 245/45 and 255/40. I would suggest you not go over 255's on the front. It will cause the car to wonder on uneven pavement.

 

A 255/40/18 in a S-03 is 26.1" in dia., a mere .1" bigger than the stock 225/45/18. In other words, it should be just fine if it doesn't rub on extreme turns.

 

I'm currently running stock tires on 18x8 and 18x9. I would have gone 18x9 all around if I was going to replace all the tires then too. Tire Rack told me 255 was too aggressive for the front. I think 245/40 265/40 combo would work well.

As for the above post about the rears fitting the front, I put them on there to check clearance for a wider tire. with the 18x9 +30, there wasn't much room for anything bigger than a 245. Had prob. about 1/8" clearance with the upper control arm.

 

I assume that the clearance issue was top to bottom and not side to side, right? That 245/45/18 you put on the front had an overall diameter of 26.7" while a 255/40/18 is 26.1". Do you think it would have cleared had the diameter not been 26.7"?

 

yes, a smaller diameter would have given a little additional room and would probably clear, since the a arm curves outward.
