I found a shop that has a set of (4) new Pirrelli P Zero tires for $700 installed. These would be installed on stock wheels, and from what I've found on here they should fit and won't look dumb.

Anyway, how do you guys think these sizes match up? It seems the front tires will have a little more tire than the rears, and that's bothering me a little.

- Fronts: 245/35-18
- Rears: 285/30-19

I believe the rears will be a 1/4" shorter than stock (26" stock vs 25.73" P Zero).

The fronts appear to be a full inch shorter than stock. One site says the fronts will be 24.1" and another 24.7. I believe the stock fronts are 25". Therefore they are a 1/4" shorter or an 1" shorter.

Any thoughts?

 

I'm using a 255/35/18 on the front and it's almost the exact height as stock. I've used a 245 as well and it's 1/4" shorter more or less. You'll need a spacer to clear the upper suspension bolt. A 235 on the stock rim only has 2 mm clearance to that bolt and a 245 is 5 mm wider on the inside. I used a 10 mm spacer. The rear is fine. So if you have the spacers and longer lugs go for it. If not, you'll have to add the cost to the bargain, and that price is a bargain for PZeros. As long as the difference from front to rear doesn't vary more than 4%, more or less, from stock the computers won't mind.

Did you use this tool:

It's quite accurate and easy. It DOES look like the 245-35 might be a bit short on sidewall. 1.3". BUT it's only .65" on the radius. Still quite a bit. You may have issues with rolling distance balance front-to-rear.. (Computer issues).

 

This is the calculator I use to compare stock to other sizes :Tire size calculator

 

No mater how I slice it, they just don't work. Fronts are too wide and too short. The rears are too short to match up with any narrower P Zero fronts unless I want more sidewall in the front than rear.
