As you will guess they are based on the images you posted, have only done  one side will wait till winter to do the other.

I just hope it will still fit once my new rear Avon CR500 205/55/13 arrive in a day or so!!!!!!

Just as I feared new tyres don't fit with the new inner arch as the rub at 2 points, more to the point the tyre rubs on the body shell and the lower edge of the outer wheel arch.

I have included some pictures as  I am not sure how much more of the body work should be cut away at the rear of the car.

 

At the start the rear of the car sat on the tyres, the tyre fitter gave me a small flap wheel grinder to allow me grind some of the body work away to just clear the tyre.

At the lower point of the rear we have 1cm clearance rising to 2.5cm at the mid point the rest is fine, so how much more do I cut away?

 

Any thoughts  please.

 

Regards

Don, I couldn't give you specific sizes to cut away but I get the feeling you might have to move the carbon arch up a bit as well to get clearance. Those CR500's have some big ass side walls on them......

Thanks for taking the time to look, I did not appreciate the size of the tyre compared to the now obsolete ones fitted to the car.  ( ie no one makes that size) 

 

Was looking at buying some fitting brackets for Miglia arches to allow me some scope for movement, did take the car for a short run and as the tyres heated up they picked up stones which you could hear grinding there way through the arch so need to do something.

You could probably fit some 175/55 CR500 or 185/55 ZZS without modding the bodywork.

[cptkirk]

What he said ^^^^^^^

 

What was the size of the original tyres?

[andream88]

They probably were 195/45 r13 (Dunlop or Continental) which are now discontinued!

[dondo]

Hi All

The rears were 195/45/13 and the fronts 175/50/13 and they were continental.  

To be honest I dont even like the look of the car from the side as Andy said the side walls are massive filling the whole space.

 

I had taken some advice from the nice men at car Z and avon tech section and they both came back with the size 205/55/13, realy having very expensive second thoughts, so tyres are comming off tomorrow and the old ones going on will try and sell the Avon CR500 to recoup some money at least that way I can use the car since we have nice weather for a change.

 

Please excuse my lack of knowlege, will the 185/55/13 still not fill the wheel arch as its the same 55 profile ? this is doing my head in !!!!!!!! why is it so hard to get tyres that just fit, end of rant.

Again any advice will be appreaciated as I have had no joy with the so called tyre experts in Glasgow.

Do you mind what make you have? What sort of tyre are you looking for? 

 

Can I assume (don't think I'm being rude here) that you don't know what the numbers on tyres represent?

Don't worry Red Hot thick skinned scots man.

I have a knowledge of what the numbers are etc, its putting that into practice to find something that fits the 8x13 and fits without having to do more cutting of the body work and moving the arches further up the body to clear the tyres. 

I found the continental sports that John the builder had fitted just did not hold the road under hard ish acceleration and the back end would drift out nicely. So I was looking for a softer road legal tyre as the car is only used on dry days and in summer.

The old tyre 195/45/13 - 19.91'' high and the Avon CR500 come in at  21.65'' 

Andream88 suggested 185/55/13 as the size is 20.85''   I now see the size of this is more in keeping with the 195/45/13 and should fit !!!!

I thought when I ordered the Avon CR500 they would fit as well, just as well that I have done 3 days overtime this week, as it looks as if more money will be spent.

I am open to any make of tyre so feel free to suggest.

Many thanks to everyone

Don

Have a look here:
http://www.avonmotor...rformance/cr500

And here:
http://www.avonmotor...performance/zzs

As you can see the 175/55 r13 CR500 have a diameter of 527mm, while the 185/55 r13 ZZS have a diameter of 530mm.
You would gain 1cm of clearance between the tyre and the arch compared to the 205/55 CR500! Would that be enough?

There is one big problem though:
unfortunately these tyres are a bit too narrow for 8x13 wheels!!!

Maybe you could try some 235/45 r13 Toyo R888 at the back with the 8x13 wheels and then some narrower tyres at the front (either Avon cr500/zzs or the Yokohama A048 or the Nankang ns-2r) with 7x13 wheels? I understand you would have to change 2x wheels but I don't see many other options...

The 195/45 Contis which were installed by the builder had a much smaller profile (like the still available 175/50 r13 Yokohama A539)...but as i already told you that size has been now discontinued.

P.S. There is another option, which is the Dmack 195-50 r13 road legal rally tyres! They have been used by Jimmorris on his build (http://www.theminifo...rged-eaton-m90/), you can try to ask him how they behave on the road....

[cptkirk]

Here is the info I collated about 4 years ago, this might help you....I can say that the R888 225/45 R13 are a good tyre and they are quite a bit smaller in height than the CR500 205's

I knew good old capitan would come to the rescue with some pictorial aid; pretty sure I've seen that before!

 

A lot of good tyre suggestions which hopefully you'll be able to measure and compare against the standard ones once fitted again; I'm not entirely sure where the "specialists" came up with that suggestion as its quite a bit bigger than the ones previously fitted, they should have at least asked what sort of clearance you had, asked for some dims or said how much bigger they were going to be!

 

I will say that the available tyre sizes are limited, I was looking for something wider myself without having a significantly oversized sidewall! Unfortunately I couldn't find anything so just kept with the 175/50 Yoko A048's and stretched them on the 8's. They actually fit better than you'd expect, but ideally I'd like something in the 195/45 range to allow a bit more surface area / grip without requiring major arch work or making the Mini higher.  

 

I'm not sure what others have founds, but upon my investigations a fair few people said that the Yoko's and Toyo's are soon to be track tyres only as the noise levels are deemed to high for road use? No more road legal slicks from them or is that just one of those stories that escalates!

[cptkirk]

Don, if you can just squeeze a CR500 205 in there, then I would look at the 225/45 Toyo R888, its not as wide and 25mm less in rolling diameter.......

 

I'd also bet you get a wider tread on the Toyo
