No guarantee your wheel is safe even with huge tires

 

ok but i was reading on internet that stretched tires increase the chance of curb damage? are they just saying that because ppl cant properly take a corner and not hit the side walk loll

 

No, people who don't pay attention when they drive ncrease the chance of curb rash. Just don't park along curbs, pay close attention when entering and leaving a a drive thru, and pay attention when you turn corners and you won't curb your wheels.

 

haha ok then i dont need to worry i know my way around with my Rx8!!
thx for the info

 

Tape measures all around to everyone that has a question.

 

Ok i belive my mind is set i will be going with a all around TSW Nurburgring Gunmetal. 18x9.5 40mm offset

 

Exactly. If you're running a x12 wheel with +50 offset you'll need AT LEAST a 40mm adapter/spacer. My 18x12 are 0 offset and will maybe have like 10mm of clearance on the inside on negative 6+ camber.

 

extremely late sub.

 

This makes sense. I think in the day I spent researching everything suspension and wheel fitment related, I confused how offset affects the wheel. I basically just need to counter the wheel's natural offset with thick adapters. Which works fine, since I'll already need adapters to make the bolt pattern work.

Time for a test fit and some real life measurements, since I think I understand from what help I've gotten here, that they'll fit with some work.

Thanks guys!

 

Post pics. That's all I can ask

 

Good luck man. I consider myself an expert in wheel fitment. I dont think this is a size you should be playing with unless you're ready to throw down some serious coin on pulling the fenders and finding someone to stretch insane tires like mine. This isnt a matter of even rolling fenders, you're going to need over a half inch pull, done perfectly, to fit this wheel. You'll also need adjustable camber and toe arms from Megan racing and good set of coilovers that will prevent you from smashing your fenders with the lips of the wheels.
I recommend against this if you're not familiar with fitment.

this.

 

In other words he is saying, that isn't a fitment for someone asking questions in this thread.

 

How about Advan Racing RS 18x8 +45 with a 25mm spacer running 225/40/18 yokohoma advans. I'm on fully adjustable coilovers. Will I have to roll fenders/remove tabs etc? How flush?

I keep searching, but everything is 18x8.5/8.75... Thanks in advance and sorry if this was a repost but I went through the first 15 pages of google and couldn't find what I was looking for.

 

I have an 05 Rx8 completely stock. Wondering if a 17x9 with +62 offset tires will be 255/45/17 all around. Will it fit? I'm going to use them for autocross and will be getting an alignment too.

 

are they mad convex wheels?

They are TR C3 in black, came off an S2000. Another set I'm looking at are some fake Cobra R's for dirt cheap. Not going for looks at all just a set to put a used set of RS3s on and run at autocross for this season only before I sell it.

Shorter tires would be helpful and get something with a little lower of an offset.

 

This is the kind of answer I was looking for. Thanks for the detail. Guess I'll shoot for 18x9.5 all around then.

If anyone's curious about the wheels, they're C6 Corvette Grand Sport wheels. Same size as the C6 Z06 wheels.

 

Alright i called the place where i want to buy my wheels and told them i have a 2005 mazda rx8 With the suspension drooped about 1inch with "Tein Stech Coils" and im looking to run 18x9.5 All around with 265/35/18.
and he said there would be fitting issued?

Is he right or just a guy who reads sheets given by mazda? and does not really know?

 

We know better than random wheel guy.

 

is that a yes it will fit ?

 

Yes, if your offset is still +40.

 

Great man, stay posted. I'll have my wheels on in the next week or so.

why do you want to run that wide of a tire? Totally unnecessary and super expensive size too.

 

i like wider tires and love the look aint that what counts

 

alright thx
