Rear Tyres Rubbing Arches

Hi,
At last I've got a GTi Cabriolet.
1990 Paprika red.

BUT offside rear tyre rubbed the arch when we were 4 up.
Not a lot of weight. Mrs Bondy and me in the front; total 20 st,
Daughter & Grandaughter in the back; total 14 st.

Ride height is 345mm front & 305 rear. Standard?

Shocks are Sachs Advantage 170 445. Standard? Fitted 10,000 mls ago.

Wheels are TSW 15" with 195/50/15 tyres. Non standard?
I haven't checked the offset yet.

Could it be a worn shock? or maybe the wrong spring? Any ideas how I check?

Cheers

or maybe the wrong spring

Spring determins the ride height not the shocker .

with 195/50/15 tyres

Try 45 profile tyres [ you can change just the rear for now]

Leave the =Daughter & Grandaughter at home problem cured . Joking a side i am running a smaller profile tyre as i need to carry passengers in the rear   But like the non standard ride height .

Chudd………

I would have thought I could carry something in the back without this problem

How are we going to get to Gaydon?

My 24 pack of beer, and Mrs Bs suitcases, campbed, mattress, 6 pillows,
hair dryer, 10 pairs of shoes,……………………….Kitchen sink!!!!!
 :dontknow:

Seriously, are 195@s just tooo wide?

Shouldn't be. Check the offsets…

How much of a rub are you getting?

does it not also matter what width rims?

Ok so a tyre width at road-contact maybe 195mm, but if you are running 8J rims then the tyre sidewall will be being forced wider as is approaches the rim?

8 inches = more than 200mm?

or am I talking nonsense?

Are 7J rims ok? I'm interested in all of this as I have some 7J BMW rims lying around with 4-stud PCD100

The only details of the wheels are:
7JJx15H2,
PCD (Blank)
ET (Blank)
There is a circular mark with 36, Is the offset?

On the TSW site they look very much like Alvis R, but 15" Alvis were 6.5  :dontknow:   

The tyre wall skims the inside of the arch, not a lot, but I need to sort it.

Any ideas folks?

7" x 15"s should be absolutely fine and the 36 sounds very much like it could be the ET which is also about right.

a few suggestions I have is a cracked/broken spring which has let that corner drop

a knackerd shock which could do the same thing

a screw/bolt holding the arch liner/ arch trim on, in just the wrong place and is catching?


I'd get under and have a check around

Thanks,

Looks like another Sunday working on mk1's

Somethings just can't get better :wink:

Cheers
