Is load rate 94 ok?

Fo several years now I've used this bunch - https://www.tyres-pneus-online.co.uk and they have been excellent in terms of choice, price and service. What you'll notice now though is that following 31.12.20 they are now unable to splay to the UK and I guess us leaving the EU will have had an impact on several other too which will affect supply for a while.

In general the load rating means a firmer tyre. So if the current spec says 88 and you fit a 94 it will be slightly firmer but should not invalidate insurance or cause issues in my personal experience. Others probably have more input.

This was taken from Michelin's website:

A. Tyre width: The width of your tyre, in millimetres, measured from sidewall to sidewall.

B. Aspect ratio: This is the ratio of the tyre’s cross-section to its width, expressed as a percentage. An aspect ratio of 65, for example, indicates that the tyre’s height is 65% of its width.

C. Wheel diameter: The diameter (height) of the wheel in inches.

D. Load index: Your tyre’s load index relates to its maximum carrying capacity (in kg). You’ll find the load rating of your tyre on the sidewall, just to the right of the diameter. For example, a tyre with a load index of 91 can carry 615kg of weight. Load ratings and speed ratings should be looked at together when you buy a new tyre. Also remember to check your manufacturer’s recommendations.

E. Speed rating: The speed rating is the maximum speed for a tyre when it is correctly inflated and being used under load. The speed rating is the letter at the end of the sidewall, after the load index number. A tyre with a speed rating of V, for example, has a maximum speed of 240 km/h.

When buying new tyres, make sure you match their speed rating with the speed capabilities of your vehicle.

Yes. But there is a point with the aspect ratio where it doesn’t go any lower no matter what the width.

I think it might be 25 or 30.

Have to leave some space for air!

Or maybe you don't.......

Not sure these would enhance the look of most cars though - might work on an "Aero"

Hi all, I had a long chat with Jamie at Brands Hatch Morgans yesterday about tyre choice as my Series 3 Aero has some 2013 year Avons currently fitted and although decent tread depth left they are obviously getting on a bit now age wise and so will need changing soon. They are 225/40 ZR18 on the front and 245/40 ZR18 on the rear. This is the specification as per the handbook. Jamie recommended three different manufacturers for the Aero: Michelin, Continental or Hankook. All of these make tyres in these sizes and Jamie was particularly impressed the grip and feel of the Hankook suiting the car. He did say that many people avoid them due to them not being a category A brand and this is a shame as his view was they are tyres which suit the car very well indeed. I'll probably get the Michelins or Continentals!

Are you certain ? 225/40/18 front yes but I think it is normally 245/35/18 rear ?

I have Mich Pilot Supersport on the S2 in the same combo as I bought them before Pilot Sport 4 or 4s could be found in both sizes.
Pilot Supersport are older now and so not easy to find. I would recommend the Pilot S4 or S4S.

The Coupe has 19" on and I went a bit potty and put the Pilot Cup 2 on the back end to try and give it some bite, sadly since then I have hardly had a chance to drive the thing.

There is another thread around tyres for Aeros in the thread as well if you want to look through that. http://www.talkmorgan.com/ubbthreads.php/ubb/showflat/Number/568719

Several people have also highlighted the Toyo's but I have not tried them.

Hi, I'm certain about the size of the rears, the Morgan Handbook for the S3 on page 4 under "Wheels & Tyres" clearly states 245/40 ZR 18 for the rears. I've also been and checked the tyres on the car and they are also as per the handbook at 245/40/ ZR18. Cheers Paul.
