What were they?

| 343.4 | It goes a bit like this | STRIKR::LINDLEY | Strewth mate..... | Tue Mar 19 1991 13:15 | 12 |
| HR is up to 131 mph, VR up to 150 ish, and ZR for more than that, but I
dont know how much more. SR is (I believe) about 110 mph.
Micheldever Tyres, who I trust about such things, advised me to fit
tyres of a rating that caters for the theoretical top speed of the car,
even if you never intend to do that speed. Thus, my old Pug had VR
tyres, even though its top speed was right on the borderline between HR
and VR ratings.
I think I've just made it as clear as mud.

Thanks John,
BTW, years ago I was recommended exactly the same thing about tyres.
The argument being that the acceleration, braking and cornering forces
were likely to be higher on a car with a high top speed and that tyres
rated for a lower maximum would not be designed to deal with these,
even if they were fine for any speeds you reached (How many people
drive at over 110 mph?).

| 343.7 | Am I wrong ? | UNTADI::LEWIS | Have Bike, will Ski... | Tue Mar 19 1991 16:51 | 6 |
| 343.8 | We could both be right | STRIKR::LINDLEY | Strewth mate..... | Tue Mar 19 1991 16:55 | 5 |
| I dont think there is a conflict between .4 and .6, since one is
talking about maximum speed ever liklely to be used, and the other is
talking about sustained , or "regular" maximum speed.

Well seeing as Rob is upset about his bike being knocked over and wants
to give as many people as much verbal as he can I will reply that I am
looking for the notes which have gone over this subject more than once.
As I remember HR is continuous to 130 mph, VR 130+ and ZR are for the
new monsters capable of sustained 150+ (ie 190-200).
The 118 mph quoted for HR sounds like the 'T' continental rating (ie
Pirelli winter 190) and the 130mph (actually 131.25 or 210 kph) new
rating for winter tyres.
Now if I get some time, I'll take a look ......

| Are you agreeing with what I said in .4 ?? I like being agreed with!
I thought I was wrong about something once, but it turned out that I
wasnt ;-)

| The E-type recommended tyres (and fitted to mine) were Dunlop ER70VR15. They
stuck like glue in the dry, and had amazing wheelspin problems under hard
acceleration in the wet ;^) Cruising at 130-140 mph, they felt *good* Mind
you, they were *extremely* fat and put a LOT of rubber on the road.
