Was searching around but couldn't find the answer I was looking for. Currently dropped on H&R springs with upgraded hotchkis sway bars. Stock tires need replacing and I'm thinking to move on up to 245/40/19 fr & 275/35/19 rr. Haven't seen much talk about this setup on the performance side though. First of all, would this setup fit on my coupé? Don't care to add spacers. Has anyone tried this setup tuned (N/A with basic boot ons) on the drag strip? How are those numbers? What about the 4.08 final drive gears? Do these tire sizes help put the power down better in 1st and 2nd gear? Thanks in advance for any knowledge given.



P.s. Getting a set of velgen wheels which will also have be 275 sized tires in the rear and 255 in the front. Forged wheels are the best bang for buck in terms of unsprunged weight and power to weight ratio however, I'm Not taking that route just yet.

 

1) It will fit no problem

2) Much more improved traction during turning and also much harder to kick the a.ss out. First gear will not spin at all.

3) Decreased MPG. More rubber on the road means more drag. Should be minimal, maybe 1 MPG

4) Increased braking power. As long as your rotors and pads are fresh, wider tires will stop faster.

5) Don’t go cheap on tires. Ever. Either grab yourself a set of Bridgestone RE-11’s or Michelin Pilot Super Sports…. They both have insane performance in the dry and wet and they last a very long time. If you want the ultimate in quietness, go for the doughboy Michelin’s

 

Thx for this. I am looking at the Michelin super sport tires. So no worries there. I am on stock brakes, upgrade would be that I'm bored and got money to blow lol. I learned the hard way about cheap tires. On my g35 i was living that stretched life 225/35/20. Every tire wall tore on me. Never again for both stretched and cheap tires. the mileage don't bother me, my car is somewhat a garage queen lol. Thx again for the reassurance. Would be a waste to get such meaty tires that the can't handle.
