I just bought the M45 sport twin spoke 19" wheels for my 2003 Sedan. I know they are 8.5" all around. I want to put 225/40/19 tires on the front and 255/40/29 tires in the back. Will the 255 tires work? Will I need a spacer? Im also planning on lowering the car a bit, I have skunk 2 springs.

Thanks

 

I would be 245 on the rears personally. However 255 should work yes.

 

Reason I'm looking at the 255 is because it is a local deal that I want to jump on.

 

The rear tire will be 1" larger than the front if you go with 255/40/19.
Something to consider prior to purchase.

 

That should look pretty hot. So how much were those M45 wheels?

 

Your tires would be .9" different and the diameter will be 3.4% off which may or may not cause issues with the VDC. Conventional wisdom says stay under a 3% difference F/R to be safe. 255/35 would be a better fit for the rear or 245/40 for the front as well. I understand you have a specific option, but if it were me I wouldn't pull the trigger.

 

turns out that the rears are 255/35/19 and the fronts are 225/40/19. Does this sound better?

 

Yep, that's perfect. You should have no issues with those sizes as I mentioned above.

 

Thank you, I really appreciate it.

 

Yep those are perfect sizes. I ran those before with no issues.


*edit*

I just re-read that the wheels are 19x8.5. That 255/35 is probably going to be too wide due to the width and profile.
I would go with a 245/40/19 all around instead.

 

Really?! Well I bought the 255/35/19 tires for the rears so I hope they fit.

 

I'm actually about 4% larger than stock. I run 255/40/19 front and 285/35/19 rear.

 

Those will fit no problem on an 8.5" rim, but will look very meaty. The sidewall will stick out farther than the edge of the rim due to the width.
