Hey Guys,

Still on my tire research phase for my 19 inch Diamond Cut wheels. OEM fitmit is 245-40-19, but just had a thought.....could i run 255-40-19? Or would it throw off my AWD, ABS, Traction Control etc....?? Also, would the 255 width fit the Diamond Cut wheels?

Treblig

It meets the 3% or less guideline. It is actually 1.19% taller than stock (according to 1010Tires) so it should work.

njsimons

It will definitely work!!

Strosek

So would that make the tire wider or taller or a bit of both.....? I'm thinking about putting Michelin Pilots Ss on my factory 19's and was thinking the same thing. It would be nice to get the largest tire possible on those rims.

Treblig

a bit of both.

The wider the tire, the better the car sticks to the road, especially during cornering.

Just be careful if you go TOO wide, you'll dull turn in response, but one size wider, ya a non issue

Edward'TLS

^^^^^ Why ?

Isn't it the wider the tires, the better the traction, and thus the better the turn-in response ?

alienstudio

would it be possible to run 255 on oem 18inch rims ?

Edward'TLS

^^^^^

255/45/18 needs a minimum rim width of 8", and the 18" OEM rim is also 8" wide.

255/45/18 will be 1.3% slower than OEM on the speedometer, which is acceptable.

Yes, 255 should work on the 18" OEM rim.

Better traction at the limit sure, when trying to maintain full g load, fine when trying to hold a constant vector, but more adhesive when trying to quickly change one.

Edward'TLS

Still don't understand.

The more the tire traction, the smaller the steering wheel angle is required for the car to change direction. This is sharper turn-in response.

However, the steering effort does increase with wider tires. The wider the tires, the more effort is needed to turn the steering wheel.

Also, throttle response also suffers with wide tires which carry more traction and more unsprung weight.

Hi Everyone,

Will I have any problems if I use 255/45//19 tires on my acura tl 2012 tecth package?
Thank you!

Tires will be a bit larger, almost 4% and can throw off ABS/VSA. Also you may run into issues with rubbing since the tire is going to be larger.

Sidenote I have been running 255 40 19 since Mile 21 when I sold the factory OEM tires to discount tires.
