There is no point stretching tyres on a 7.5j. Its far too thin!

You need 9j minimum on an e36.

You only stretch tyres when the rim is poking out the arch.

Go on google and type in tyre stretch calculator.

Btw. You do realise your car will handle crap, be really uncomfortable and generally unsafe at speed with stretched tyres don't u? Its a fad I can't wait to see the back of.

You need to have a look at some of the guy's projects on here. Disco Stu's comes to mind.

Wrong. You can make it look good with almost any width. It's the offset that pulls it off.

I have to question your experience with this? I run stretched tyres yet my car handles very well. It's perfectly safe at high speeds and isn't any more uncomfortable than 'normal' tyres.

The downside of stretching tyres is that you reduce the contact patch but this isn't really an issue with everyday driving unless you push the limits constantly.

The key to maintaining safety is to keep a close eye on tyre pressures. People I have spoken to run anywhere from 32psi to 38psi.

I do agree however that you can go too far with stretching.

Yeah, it does look the dogs b0llocks when its been stupidly strectched. But most of the time when this is done these are for show cars, and 99% of the time the wheels are either fitted at the showground or the car is trailored :thumbsup

I had 225-35-20 tyres on the front of my e60, on a 9j wheel and unless there was over 45psi they were slipping off the rim, so i am now replacing them with 245-35-20 so i can drive the car. This is also the correct fitment for the wheel. I could also go 235-35-20 but after paying for 2 tyres and having them both loos pressure and slide of i am not taking any chances.:frown
