Arch rolling or will I get away with it?

Just wondering, I shall be purchasing some new wheels soon at 18x9.75 et20. Now will I get away with not rolling the arches or will I have to? I have/ am waiting for H&R springs at a 30 mm drop too.

 

Any help appreciated

 

Thanks

Might get TC issues without a staggered set up....

 

Why would that be mate?

 

As long as the tyres are staggered you will be fine! :)

 

I wasn't going to stagger them! Why is this a problem?

 

Its not

 

Plenty of people run a square setup without issues

Good to hear, but why is it that people do have problems? Like what's the technical issue behind this?

Traction control measures the speed of front - rear rotation, the rear should be turning a few percent slower and once they begin rotation at X ratio the traction control will kick in.

 

The correct sizes for 18's are 225/45 and 245/45, but i believe 235/40 and 255/40 work too?

Oh yeah, I'll be going 275/35 all round so very slightly stretched

 

275 at the front is possibly too much. I'm aware of the concept of stretching the tyres on the rims, but I always thought that you fitted a narrower tyre in order to squeeze it under the arches, surely a 275 tyre on a 9.75 inch rim is going to be bulging outwards, ie stretched in the wrong direction?

Hey man, I have a picture with the exact set up on a 350:

That's 18x9.75 all round with 275/35 tyres on! Very very slightly stretched :)
