Will my warranty be void when I have 245/40/18 installed?!
Do I have to do the switcharoo with the old set every visit to Acura for service?

 

No.

 

you are fine
Its only an issue on mods if you slam the car-- then go in complaining of cv joint noise!
Well no duh you are going to wear those out with it dropped! that one is on you
but the trans fails? thats on them
There are guys with superchargers getting warranty transmissions- and you are worried about a little tire size change hahahahhaha thanks I needed that~

 

the techs make sure to `thoroughly test drive` cars with good tires and suspension~

 

Thank you for the reply(s)!!!
I did call the Acura dealer...they said no.
I am starting to get resistance going into third gear. I didn't want to pull into Acura and have them give me the boot for the tires, not being thier "recommened size".

I just put RonJon Inspyre's on with Yoko ADVAN S4......WOW!!!!!!

 

245/40-18 is near factory spec, maybe 1% if that off

if you rolled in with 245/35-18 or 245/45-18 i would understand them saying some bullshit about components such as a speed sensor or what not, but you are near spec, so as mentioned before should be no worry
