Are the thoughts on 6" fronts and 8" rears the same for 15" wheels rather than 13"? as i can only really find minilites available in these sizes. Also whats the optimum tyre sizes on these rims? Thanks
I'm going to run them, I have the rears not the fronts yet
Was thinking 195 50 up front and 215 50 or 45 at the rear
Which wheels do you have, are they available in 15x6?
beaver34, I'm still looking for the 6" 108 PCD alleycats, looks like you've had no luck either!

ok, what are optimum tyres then for 15" rims, all i know is caterham use 6and 8" rims, but in 13"dia. Id copy their tyre size, but there might be a better profile on 15's
205/50 x 15 front and 225/50 x15 rear..........you could go as low as 195/50 x 15 front....I don't think I would though
I also wouldn't go for a lower profile ie 45 as the ride would be terrible

Thanks, what size rims would they suit best?
7 and 8 inch..........I've used that combination on loads of cars...........
I think Dax used that combination,and went up to a 10 rim with a 285/40 x 15, which is far too big with such a light weight
ok ta, just want to get it right from the start so i can drop a 20let in when im ready for it.
205 and 225 is massively over tyred for most sevens. What power are you running?
Probably 175hp to start then 200-220 if i do the conversion
Check out the Donkervort site and also ,I think Mohr(german)that is more or less a Dax
Style of wheels?
Compomotive do a ML,very similar to Minilite,there is still a Performance wheel in that pattern(personally I don't rate them)
or what about the TH from Compomotive
The process should be as follows:
1) Work out what type of tyres you want to run. Semi slick, road, soft compound, hard compound, etc.
2) Work out which tyre widths front and rear will be suitable, based on type of tyre choice (the wider you go, the cooler they will stay). Don't
think wider tyre = more grip like most people do. Be sensible with your tyre choices. Something like a 185 front and 205 rear will work well with a
semi slick. If you go much wider you'll struggle to heat them. On a road tyre, you may not want to go as wide, since the compound will be harder
and therefore harder to heat.
3) Based on your ideal widths, look at the tyre wall height options. Most 7's run a tall sidewall which works well.
4) Now you have picked your tyres, go on to the tyre manufacturers website and look up the tyres. It will give you a minimum, maximum, and ideal rim
width for the tyre size. Best to start with the ideal width if possible, which gives you room to move up or down a little in tyre width if you need
to.
5) Work out your offsets based on rim width.
Tyres weigh a lot. They can often weigh more than the rim they are placed on, so make sure you don't over-tyre the car, adding unnecessary weight
to all 4 corners of it when you do not need a wide wheel and tyre in the first place.
Hope this helps.
