Hi all, the metric tyres on my mondial are 220 55 390 and finding them can be a bit of nightmare, I need two for the back and can find some very reasonably priced 220 65 390. I know these a little higher (if thats the right term) but it seems to me like that would fit perfectly. Has anyone got any thoughts on this?

Any advice greatly appreciated.

thanks
Darren

Suggest you try:

Check your tire dimensions.
I think the correct numbers are 240/55 VR 390, all round.
The original tyre was a Michelin TRX.

+1, just checked a copy of the owners manual. Only difference is in recommended tire pressures. Fronts are psi 33 and rear psi 35.

So it is :-)
TRX tires are quite noisy compared to modern tires, and obviously of older design, so less "good" than a good modern tire (Michelin, Yokohama etc)
You may consider updating to Superformance Replica wheels and modern 225/50 R 16 that gives the same width on the road and circumference (±2%) than the old setup, so the gearing/speedo remain correct.

funny: The T is getting a new set of shoes this week, but my sizes are different than yours and diff front vs rear.

Just put on a set of Nitto's for the 456 and they are performing very well...VERY nice mfgr....might check them out..but for the Mondials, unfortunately no go.

[Darren MondialQV]

It does seem odd, the car sticker in the window says 240 rear and 220 front. Eurospares says 220 all round and mine has 220 all round.

I have found some nice part worns but they 230 55 390 does anyone know if they will be ok? I gather if the car can have 220 and 240 then I guess the one between will also be ok.

Or if I do go for the 220 option will a 65 be ok. This is only height..am I right?

Dont know much about tyres to be honest.
cheers

Darren;
Dealer might have stuck on different set for rear. Actually, in my manual the tires a larger in rear

Just checked the owners manuals. They moved back to "normal" tire sizes for the Mondial t. Also the rears are larger than the fronts: 205/55 ZR16 Front and 225/55 ZR 16 Rear.

[afterburner]

The 8 and QV had metric wheels of same dimensions all round.
The 3.2 had metric or imperial wheels, depending on the market.
The t only had imperial wheels.

The 3.2 and t also had narrower wheels at the front than at the rear.

The wheel alignment for same-size vs. front/rear different size is NOT the same.

So, should you convert an 8 or QV to different size front/rear, you ought to redo your alignment accordingly to benefit from the change fully.

thanks guys. I am going to stick 230 55 vr390's on the back because I can get these much cheaper as they were a bmw size in the 80's I believe. the 55's seem a bit more rare and command the higher prices. If the car should have 240's on the rear then I guess Im not far wrong with a 230.

Im sure it will look at bit more meatier from the back also compared to the 220's currently on there.

I downloaded the tire calculator for my iphone, its a great bit of kit for 59p.

The Mondial 8 I used to own had 240's all round and the 308 is 220's all round.

Had the tires put on today, 2 part worn 230 55 vr390 over the moon with them. They cost me 75 for both and had them balanced and fit for £20. Think I have saved myself a lot money. I do love eBay.

those are new tires, right? did you check the side wall for mfgr date.

Tire age is critical. Over 8 years is a no go in my book.

[Gcalo]

Tire age is very critical as is proper sizing.

Get the true OEM size and then use this calculator to know for sure. Don't guess:
