Talk Morgan Forums Morgan Sports Cars Morgan Aero 8, 2012< Plus 8, SuperSports, Coupe & Aeromax Tyres

Given that my car (2003 S1) has had the same tyres on for at least 2 years (probably much longer) and only done a few hundred miles on them I suspect they are out of round and causing vibration.

So, do any of you have any recommendations as to tyre choice and also if 225/40 is the limit in terms of width.

Many thanks in advance for your assistance.

Been quite a few threads on this subject. See:

I ended up with Toyo Proxes T1 and am very pleased with them for all round use.

Yeah, I did find that post but it is inconclusive. What is the general concensus for a road tyre (are R888s really practical for road use?). Interesting to hear that you like the T1Rs as they are among the best value out there.

Also, sizes, do we have to stick to 225/40 all round, if not what can we go to?

As this is my first Aero I cannot bring any experience to which tyre is best. I have used a lot of different tyres including Comp/Track in the past though.

I had a number of tyres on my Skyline 33V when it was around 550bhp and can share some experiences.

1. Comp/Track Day tyres often assume "STIFF" suspension and so have slightly more flexible sidewalls which makes for an odd road experience.

2. The milage you get out of a "Soft" comp tyre will be something in the region of 1000-2000 miles on the driven wheels, 2000-5000 on the medium/hard version in my experience. You had better be rich if you want to use them on a regular basis for your road car !

3. They are only "better" when up to temperature which can be hard on a cold/wet UK road. Otherwise they are grouchy and have a tendency to introduce you to hedges you have never met before.

4. They require very careful pressure management to get the contact spot right, usually slightly lower than I expected compared to standard road rubber for mine.

All that being the negative stuff. On a good warm day, once you have got some temperature into them then they do provide a significant increase in breaking and final 90% grip which continued to surprise me all the time.

You do need to be willing to put the effort in to see the best out of them.

I used Yokohama A048 on the Skyliner as I got a steer from one of the racing people from Austrlia when I was down under once. I never had trouble deploying all of the power and watching peoples faces even after they were warned was quite interesting.

I had to use the Skyliner every day so it was difficult to face the cost of using comp tyres all the time, if your Aero is a weekend blaster then it could be a lot more practical. Just think through your % time in hot/dry/clear roads or track versus real world driving and how conflicted the demands on your pockets are. I loved it when they were on.

I have just got Yoko Parada 2 put on mine as I cannot face paying to replace them that often however the temptation to put 888 was very very high. When it arrives I will be happy to share my experience.


HTH.

In all honesty, not unless you are only running the car on dry days.

888s offer insane grip on dry surface but can be a little skittish on damp, wet or cold roads. In these conditions, you can keep the car on the road; however, you would need to be completely focused on the task and not take any liberties with the car. They are designed for track use and therefore maximum contact patch - the design has limited option for dissipation of surface water. They are also very soft, so as Alistair mentioned, lifespan is radically reduced. I have heard of people eating through a set in 200-miles on track. (basically 2 days of 12-sessions (5 laps per session on 2.5 mile track)

T1Rs are excellent as are Michelin Pilot Sports (MPS) - Michelins always cost more but people in the trade also feel that the cost equates to a longer lifespan; therefore, it equals out.

I rant the MPS on a track car and found them excellent both on road and track (and in all weathers); however, the downside was that there were quite sensitive to heat on track and when the pressure increased, they could feel skittish.

The thread Speedmog pointed you to is an excellent one - any other questions, just ask.

All helpfull stuff, I'm guessing that an S1 with its rose jointed setup would react well to a softer sidewall.

Anyone got any information on maximum tyre sizes? This seems to be the most elusive piece of information.

Have just put them on my car. After a few (500 miles or so) of running in I am very pleased with them. The wet weather grip is phenomenal, or maybe my last set were just terribly bald

I would highly recommend them.

Sorry I cant comment about sizes as the S2 is slightly different??

Here is another good thread on tyres for the Aero 8.

And here is one about tyre width .

Used S02's on my M3 Sport Evo, they were excellent
i would rate them as the best all round tyre i have ever used.
My M3 was a similar weight to the AERO 8 (1200kg)
