You will have no problems. I run a 15X6 w/205's and have never had a rub. My car is also lowered about 1 3/4" below stock. Looks good, too!

I have run both 205 50 and 225/45 15 on 6" and 7" rims with no problems. It will look a little funny if the car is at stock ride hight and the speedo will be off some.

Question

Hi I have woundered about the rear tyre size myself and I was going to raise a topic, so I hope you don't miind me jumping in on this one .
I have two sets of wheels the stock 15 steels and 14"fusch comfort wheels what size do you recommend for these.

I do not want the rears to put out my speedo as we have loads of camera's in the UK. I have lowered the car.

Do you have a photo's of the car with the 205's and when you say 205's are they just 205/15's ( and not like 205/70/15 or 205/80/15) I have bought all new tyres and I think the guy sold me the wrong set grrrrrrrrr. one front 165/15 (beetle) rear 185/70/15 see pic

I am looking for 15 " fusch but I live in the UK anybody got any for sensible money??

912UK:
The original 165\80 or 78\15's are getting hard to find, but give the car the original look (& handling, good or bad.) A good crossover is the 205\65\15 which is very close in overall diameter.
This also crosses with the 185\70 optional "S" tire. As for the 185\80\14's for your Fuchs, they're getting hard to find.
As Green mentioned, slightly different sizes or aspect ratios can drastically change the appearance of the car - too much wheel well showing or tall tires crammed into the openings and speedo error. It all boils down to whether your priority is originality or performance.
Check the links below for cross-ref. Here in So.Calif. we have the advantage of getting Cooper 165x15's dirt cheap through VW performance shops, but I doubt that they're available in the UK. Hope this helps.

Check out these two tables: (hope the links work.)

tire size calculator

Here's a cool link to a tire size calculator. You can compare two sizes and it show how much off the speedo will be with a new size.

I run a 205/55ZR-15 on 15x7" Fuchs on all corners. I'd like to put 225/50's on the rear with a 8" Fuch but the offset is a little off and rubs (yes, I tried). If I could find a 8" Fuch that sit further in towards the suspension, it would be fine. BTW, my 69 sits really low which might be the cause of the rubbing. A stock height 912 should be able to accomodate a 225/50-15 easily I would think.

Don't need the 8 inch rim.If you want to ru the 8s you can have them milled down some. Most comp and street 225/50/15s fit just right on a 7 inch rim. I ran 205s all around untill I bumped up the power some and then went to 225 in back. (both 45 and 50 ratios work well and fit , the 225/ 50s better for the longer tracks such as VIR or Mid Ohio) With the right T bars and the sways tuned to balance out the over/under but be as "loose" as posable the 12 tracks well and keeps up with some of the best in the turns even with its "primitive" T bar springs . It is posable to over tire a 912. There is a trade off between traction and HP and a light low HP car might not be able to heat and compress to the track a too wide tire. unless the suspention is set just right you can end up with less contact patch.

BTW Good looking ride!

I just want to tell very body in the world I have after 3 years on doing up my 912 got it runing and I moved it only a few inches and it works..................

So I will have to get those tyres sorted out for the rear. Your orange 912 looks rad but I can't go that low and I think for me the rear tyres look too big but it looks well cool.....

Mark

I will be posting a new topic as I had chuffing form one of my carbs ,on tick over but not when the revs are on, only on tic over. Carbs Just been totaly rebuilt. It fires up as soon as you turn the key. much better not like out other one.

but still chuffing or more like a slight miss fire?

any ideas
