i think that if you dont run proper ratio's it will throw off your speedometer. Using that link thats stickied on the top of this sub-forum it says that your speedometer reading with those profiles are gonna be 3.6% too fast, so you are going to be traveling at 57.8 mph when your speedo reads 60mph.

anyways i do have pics of 245/35/19 & 275/35/19.
let me see if i do this right..









hope this clears stuff up. ;]

 

So I would be better off keeping the 255/40 on the rear and just switching the front to a 245/35 ?
I had thought about that, but I really like how the 235 handles in the front as opposed to the 245

 

or what about keeping the 235/35 in the front and running a 275/30 in the back?

 

245/35 and 255/40

 

That is what Im going to do
Thanks for your help redlude!

 

That's what I did too. I'm having them installed this morning 245/35 and 255/40

 

i need new rears..i guess i should go 255/40/19 on t1r's?

 

I've got 245/35 on front and 265/35's on the rear...continental contisport 2's. Tires are holding up nicely and look great!

 

IF you running OEM 19" what size tires would you go with if your car is 1.2" (f) 0.9 (back) drop..An you want to cover up a good amount of gap.. but at the same time you don't want too much tire showing?

 

thanks for the info guys.im getting new tires this week. T1R's or FK452's?

 

I got the 245/35/19 on the front and kept the 255/40/19 on the back and my car feels great. No more trouble codes, brakes feel nice, Im happy!

 

245/35 and 255/40 seems to be a good choice for OEM 19's but what are some tires that will last.

 

T1-R's are the MOST popular choice by users on this forum, just from all the information and stories I've read.
I think people consider the Toyo's as the best "bang for the buck". There are "better" tires out there, but they cost alot more, and the tread life on the Toyo's is good. 15k-35k in most cases, from everything I've read. Usage will vary according to your driving style, naturally.

Search...there have been probably more threads on "What's the best tire?" than anything else on this forum

 

Bridgestone Potenza S03s ROCK!

I used them before on my Acura CL Type-S

and now I'm using them on my G35

They last quite al ong time and they're really decent so far as traction goes. GREAT all-weather tire and great in the rain.

Bridgestone has discontinued them to start up a new line so they're half-off everywhere!

They used to be REALLY pricey but I just got a set for front and rear for $800 shipped. on these bad boys.

 

i have a 05 coupe, and thinking of putting on 235/35/19's in the front and
255/35/19"s in the back. I am basically going up one size from my oem sizes. do you think there would be a problem with that. please help. first purchase of tires for my g. Thanks!!
