Tyre advice (one more time) for 6 & 8 x 13

[7SW]

Hello,

 

I did a search in several posts but I'm a little bit lost.

I just got a set of 6x13 and 8x13 ET24 R500 8 spoke wheels.

They are currently fitted with CR500 but I would like to change them as, I need something versatile (lot of long tours and mountain roads); I do not plan to put the wheels onto a track (or very rarely).

 

The sizes of these CR500 are:

• Front: 175/55R13 75v
• Rear: 205/55R13 85v

 

I plan to get Avon ZZS tyres as I am satisfied with them on my current wheels (15'' 10 spoke).

Going to Avon Tyres site, the only available size for 13'' wheels are:

• Front : 185/55R13 83W XL
• Rear: 215/55R13 88W or 245/50R13 93V

If, for the front, no choice is given; for the rear axle there are 2 possibilities.

What could be the best setup 215/13 or 245/13?

My Cat is a 1.6K SuperSport so, far under 200BHP  ;)

Thanks for your help

215 on the rear.

The cr500 is a great tyre that's sadly missed.

At that power level why the big rears?, you car will be overtyred, and just pile on understeer, each to their own....

R888R  185/60/13 & 205/60/13  more than adequate for my stable of ponies.....

for a stock 1.6 I would suggest 185's all round would offer a better balance to the car

#3 Just out of interest, why does the lower powered car 'pile on understeer' and not a higher powered car?

I’ve got a set of SLR split rim wheels on my 150bhp Supersport. Cosmetic reasons only, they look fab! On the road, I’ve not noticed any tendency to understeer.

re #5 I'd have thought it's more that there's no way a low power car to overwhelm the rear tyres under power, so you'll only ever get understeer. As others have suggested, at 135bhp I'd think a square setup (185 all round) would make more sense. As a bonus you can rotate the tyres to even up wear/life.

Hello,

 

Thanks for your comments.

Fitting a 185/13 tyre onto a 8'' wide wheel is correct?

[Wrightpayne]

Nooooo!! You don't want the stretched look.

What everyone is suggesting is 6" rims and 185/60 tyres all round.

A few years ago I posed the question about tyre widths and bhp - when do you need to go bigger on the back? The general consensus was 200bhp.
