Wheels doubt

[spynish]

Hi!

I'm thinking in buying 15X7 wheels (either Enkei or Kosei), but I'm not sure if I can use the stock tires. I think I should use bigger ones, like 195 in the front and 215 in the rear.
Do you know if I can use stock tires?
Another question, I've read that with the same profile everywhere the car oversteers easily, is this correct?
Can I compensate this oversteer with a bigger rear profile (like 225)?
Thank you for your help in advance!   s8) s8)

it's not the profile you need to worry about from an oversterr understerr perspective but the width.

as long as you keep teh stock stagger or there abouts then you sjhould have no issues.

Thank you Mark!  s:wink: :wink: s:wink:  

So there's not any problem in using 15x7 in 4 wheels...
I thought it was...  s:? :? s:?  

But thank you!  s:D s:D

it's not ideal, but since most wheels aren't available in split widths, most people don't worry about it.

that said a 185 on a 7" rim will get very stretched, so I wouldn't use that tyre.

205/50/15 front and 225/45/15 would be good assuming you can get them.

kosei do 6.5" and 7" widths in a lot of their wheels.

if possible best to do this.

Hi

Just one question more: I've always heard that wider wheels have a negative effect in both fuel consumption and performance. "How" true is this? I mean, is there a significant difference? Will I notice it?

I had also thought in 195 in the front and 205 or 215 in the rear... Is a good comb?

Thanks again!

I guess wider wheels = heavier wheels.

Heavier = harder to move = less acceleration and more fuel needed.

Bongo:

In this case wider is not heavier, at least that's what Toyo says:

A 215/45R15 tyre 17.6 lbs.
A 205/50R15 tyre weighs 18.5 lbs

And I was referring to the area that contacts the road, there is more rubbing with a 215 wheel, though I think this may not be significant...

Sorry, misunderstanding, thought you meant the actual wheel, as in the alloy.
