Hello all,

Just been going through my parts list, and seeing what i need to buy for my Haynes Roadster project.

The 1 thing i want to start looking for is wheels and tyres.

I just wondered what your views and opinions were on what is the best size wheels and tyres for handling on a Haynes?

I'm not bothered about ride comfort, just purely for road holding and handling.

I know there are other factors, such as suspension set-up and other variables.
I just want to start looking for wheels ASAP, so i have a chance of coming across a bargain.

Cheers Frank.

In a light car 13". Does depend on whether they'll go over your calipers.

I'm going to try a set of 13" Escort mexico rims on the hubs, but I've been told they won't fit over the rear discs.

What would be the ideal width for the wheels?

Im using 225/55R16's on mine and then upgrading to 245/45R17 after IVA. Not the norm but then nor is my car

The accepted wisdom is smaller is better - i.e. 13" rims with 185 front tyres and 205 rear tyres.

13" and 15" will allow the widest and usually most economic tyre choice.

I suppose i should have mentioned, I'm running a 250bhp(to start with...) BMW 2.8, out of an E36 328i.
So, i need to get the power down.

I'd definitely go with 13 inch wheels, and only go larger if you have to. Rear brake clearance is normally the problem.

You have such a huge range of tyre options in 13 inch, and also you can run a tall sidewall with 13 inch wheels, allowing the tyre to comply with the road.

The wheels are also a bit lighter than 15 inch wheels. Even 1kg per wheel is a good thing to save since it's unsprung, and it's hard really to save unsprung weight (unless you have deep pockets and like the idea of carbon brakes LOL).
