Im looking to buy some old style rs4 wheels and lower my 9n 60/65 on FK highsports. These wheels are 17x7.5 and come with 215/45 tyres but looking through similar forums people seem to suggest 205/40's. Is it possible to get 205/40's on 17x7.5 wheels?

Yeh I'd recommend 205/40s, they'll decrease the chances of scrubbing, plus look soo much slicker

Thats good to hear!
Does this mean the tyres will be stretched though? or will they fit properly?
Ive not got a clue about stretched tyres and what the drawbacks of them are!

205/40 is the industry standard size tyre to fit on a 17x7.5" rim

So no they wont be stretched.

By industry standard I mean that if you buy a wheel and tyre package from a shop a 17x7.5" rim will come with a 205/40 tyre 99% of the time

Have a look on a tyre manufacturers website (toyo or yoko) and look for the tech specs section. It will usually have a column for what widths a particular tyre can be fitted to. For a 205/40 its usually between 7" and 8". Thats what the tyre will be 'rated' to go on however some people (myself included ) have ignored those 'recommendations' from time to time

Stretched tyres are usually used to avoid rubbing/to look good. They will not improve your handling or ride in any way though, theyll ruin it!

If you really wanted a slight stretch on a 17x7.5" rim go for Continental Sport Contact's (think they are SC2's) in a 195/40/17 flavour. Will look good if your going to slam it and will at least retain some 'give' in the sidewalls

Ive got 17x7.5" alloys with 205/40's on and my coilovers are as low as they will go (ive also removed the adjuster plates from the rear's to drop it a wee bit more). It rubs but I can live with it

Pics: (because im a shameless pic whore!)





Hope that helps

I disagree im afraid. It depends a lot on the make of tyre you fit. I had yoko a539 205/40 on a 7.5 and it gave a slight stretch. Now I have falken rubber and the stretch is much more obvious.

I think that 205 is fitted to a 7" rim if you want no stretch at all. My comps are 7.5 and there is quite a bit of stretch, the lips of the rims stick out quite a bit from the tyres.

Cars lookin good btw Pidge

Thanks for yours responses!
Think im just going to stick with 205/40's at first, might have to get sum 195/40's in the future though

BF Goodrich 205x40x17 sports on a 7.5 rim:



I recommend the tyre - great grip and I've had them on for nearly 20k now!

Yeh 205/40s will be fine for now mate, pidge yours cars looking awesome

Tim what size tyres have you got on your Mono's? Trying to decide what tyres to get for 8.5x17" Schmidth TH's.

I know you mean the other Tim, but I reckon 205's on a 8.5 will give you a nice stretch, or 215's a subtle stretch.

I've got Toyo 195/45/15s mate, my alloys are 15X8

I think 205x40x17s will do the job!

although you might be governed by cost anyway - how much are 195x40x17s and do they even do them?!

There are only 2 or 3 manufacturers of 195/40/17's. Continental and Pirelli defo do them as a couple of friends have had them in the past. IIRC they retail at over £100 a corner for both makes

Thanks for your replies, on 7.5" wide wheels 205/40/17 looks nice. So the same should give a great look/nice stretch on 8.5" wheel. I'll lookout for 195's, but I dont want a mad stretch.

I wonder what size Chris has on his redwood 9n?

one thing to note: my Yokahama Paradas have more stretch than my BF GoodRich tyres did. So you might want to compare makes if you can.
