Ordering tires online today or tomorow. Tire rack recomends Tire Size Front: 225/40-18 | Tire Size Rear: 255/35-19. I still have OEM rims is this the best size?

I know I have seen threads saying people have had clearence isues and sugestions would be helpfull.

 

These are the OEM Tires sizes. You will have no issues with them.

 

Zahanma is correct. Those sizes are what the manufacturer put on the car originally. You'll be happy with that size and you're guaranteed not to have any issues.

However...
I would recommend NOT buying them from Tire Rack. I know the prices are good on Tire Rack. I know the selection is good on Tire Rack. But: every time I buy tires from them, at LEAST one of them is messed up.

For example: I bought four tires for my daily driver. They were nothing special, just Continental Extreme Contacts (Z Rated all season tires). One tire was so heavily out of balance, the tire shop couldn't balance it. When it was mounted on the rim without weights, it would roll by itself and always stop at the same spot - like it had a lead weight glued to it.

I thought the tire shop I went to was just giving me crap because I didn't buy the tires there, so I took them to a trusted friend who owns a shop about an hour away. He had trouble too. I ended up returning the tire to Tire Rack. He said he sees this all the time: out of four new tires usually 1 is bad, frequently 2 are bad!!

Go to someone you trust and have them order the tires you want. You might pay a couple bucks more, but you'll get quality tires - or the shop will return them before they ever mount them.

 

Oh my. That's the first I've heard of problems with Tire Rack's tires. All 4 sets I've purchased from them have arrived fast and in perfect condition.

I recently put on 235/40/18 and 275/35/19 and have abosolutely no fitment issues. Also they look great.
SRT6 with stock wheels and suspension.

 

Is there any reason that these bigger tires couldn't be used on a regular Crossfire? ?
I'm waiting for my stock 7 spokers to come back from the chrome shop and I'd like to put the 275's on the back and 235's on the front.
Anyone know for sure if this can be done without any issues? ?

 

I run these on my NA 6 spd. No problems.
The most that can be used on stock rims with no issues.
The 285/35r 19 on back will work just a hair over recommended width on our stock wheels.
A 305 will fit on back with wider aftermarket wheels.

 

Excellent, thank you so much!
