I need the experts on this one!

My fronts are 225/45w r18 and being replaced with 255/40w r18
My rears are 245/45w r18 and being replaced with 275/40w r18

will this mess up the slip sensor? or abs?

I am keeping the stock rims!

 

That combo should work perfectly as it maintains the stock OD and stagger.

 

As Dave says, the overall diameter on your new tires maintains the correct staggered measurements so your car’s VDC won’t be a problem.

Just curious though… What is the width measurement of your 18” wheel?

He mentioned stock rims so they're probably 8" wide, maybe 8½ on the rear if he's got track wheels. I see where you're headed - that 275 on the rear is way too wide for an 8" wheel.

 

^^ Yes… you’re correct. If that is what he’s planning to do, I would approach that configuration with some cautions.

Whats the widest I can go in the Rear?

 

Im not sure what the width measurements are but maybe you guys would know...it is the stock 2003 18" rims that come with the z?? can anybody tell me the widest I can go with that???

 

Whats the widest I can go?? can I go 265??

 

235/40/18-Front
255/40/18-Rear
-OEM+0 sizing
This would seem ideal for the 03 18" wheels.

 

so 255 is the widest I can go in the rear? I want the absolute widest because Im due to go up against a quattro s4 soon and I need the traction!!!

 

Hint: you want wider tires get wider wheels.

 

245 in the rear , its only an 8 inch wheel.

 

is it 03 18" wheel? than its 8"

 

So you want some bigger tires so you can race. You are maybe getting a 1in more width with a 275 tire, if that. They recommend a 9.5in tire for a 275. you have 8in rim. The biggest they recommend on an 8in rim is a 245 (tire rack and factory specs)

 

If the rear wheels are 8" wide, I'd not go wider than 245. If you have 8.5's though, you should be fine with a 255/40 18. Those are the sizes I'll be running on the BBS RE 18x8.5's I just bought. Prob 245/40 front and 255/40 rear. Just buy a quality, sticky 255/40 rear, and traction won't be a problem.

 

thanks guys....so what I learned is the widest I should go is 245's in the back!

 

245/40 front

265/40 rear

 

-i just measure my 04 ent...maybe i read it wrong but i think im 8.5 on all four so im not staggered wheel wise but the tires in the back are staggered by 10

 

Alberto you saying in fact i can go 265's in the rear with my 03 stock rims???? despite what all these z gurus are telling me?

 

According to Nissan's Specs. the wheels are 8" wide, front and rear, unless you have the forged wheels from the Track model. Those where 8.5" in the rear. My recommendation would be 245/40/18 front and 255/45/18 in the rear. I would go no wider in the rear, and no lower in aspect ratio. You will maintain the stager, and you will reduce some of the car's understeer.
