Hey Guys,

I wanted to put a wider tire on my OEM 18's. Wondering if 245/45/18 will be okay?

thanks for the help in advance!

Kris

yea it will fit, but you will find more choices and it will be cheaper if you go 245/40. Most people here go 245/40.

245/40/18 is a very popular upsizing option for the stock wheels, and your speedometer will only be about .5mph off from the stock tire's diameter

245/40 is works fine. S'what I have on mine atm.

thanks for the help guys,

I got a set of 245/45 winters thats why.. (I know i should stick with 225 for winter) but i got a good deal on these winters.

Thanks
Kris

If 245's will fit on the stock wheels, will that be too skinny for 18x8.5? i'm ordering some enkei RP03's tomorrow and i want to make sure i get the right size. should i just go with 255's??? :dunno:

<- has 245 tires on stock rims. Love 'em :)

My thoughts -- I used 245s on my 18X8 OEM wheels this summer and found that I could not get the all the tire on the road at track events and wonder if squeezing them onto the OEM wheels caused that. I know there is a lot to that but my feeling is that 8.5" wheels might actually help the tires to spread and 'breathe' so you can use all the tread...Therefore, 255s on the 8.5" wheels might also squeeze them...

245's are the way to go with our OEM wheels.

Anybody tried 225/40 with stock? Besides better handling..how much off is the MPH?

i'm actually gonna go back down to 225/45/18 when these 245 RT615's wear out by this spring, I lost 1mpg on average in fuel efficiency as result of using wider (and probably heavier) tires than stock specifications, and I'd like to get that 1mpg back lol

^^^ Omg...

Hahahahahaha...now THAT is funny ^_^

The mph will be off by ~2%. In other words, when the speedometer reads 60 mph, you will actually be travelling ~58.8 mph and, when the speedometer reads 100 mph, you will actually be travelling ~98 mph, etc.

Kewl. Thanks!! Got a set of them vs. 245/40: saved $40/tire!!

what kind did you get???

Got the Kumho Ecsta ASX (all-season): $85/tire vs. $119/tire. Was thinking about the Continentals..they were $125/tire...but...@$40/tire difference..chose the Kumho..afterall, they are only all-season..so performance-wise, won't be that much difference to justify going with the 245..

Where'd you get em for $85/tire?

edit: nevermind... you didn't get the 245s and I did...

Tirerack.com

Actually, they will be $95/tire once America Tire/Les Schwab match price. Otherwise, if you try to buy locally, they are normally $120 or so/tire. For the NW environment, all season makes so much more sense than summer. If only I was rich....heh!

You got 225's though didn't you? I got 245's through TireRack, I think they were $119. Now that I think about it, I did, however, send in the $40 rebate... did you?

245's are hotttttt :)

No..don't think they were running the rebate when I purchased the 240..would of been nice though ^_^

Good news!!! The Kumho Xpress Yourself Giveaway offer is still good until 12-31-06!! The offer is for free sunglasses or headphones or a $40 Rebate. Sneaky.. they are "giving away" a rebate :rolleyes:

You just have to submit it within 30 days of buying certain tires. It doesn't show up on the TireRack or Kumho sites anymore though...

You need to print out the rebate form and mail it with a copy of your receipt - see PDF file below.

Forty bucks back!!! :rock:

You rock Gr8Lady!!! Woohooo!!!

thanks man!!! i just about new kumhos!!

Any tire that is wider than the supporting rim width..wont perform as well as it would on a rim with a matching or wider wheel width..strictly speaking.

I wouldnt go wider than 120% wheel width on tires for performance driving. If you do..they'll scallop, wear, heat up funny..etc. And have a nice side to side shimmy in transitions.
