Tyre choice

Recommended Posts

Hi guys,

My car still has the tyres that it came out of the factory with when new (still have about 4mm of tread depth), I need to change them as I dont really fancy doing any high speeds on 26 year old rubber, there is very little grip in the wet and it's sooooooooooo easy to loose the back end, even when changing gear in a straight line.

What tyres do you guys use.

Blimey you must have a sub 7k mile car if you're on the same tyres it came out of the factory on...

I use the old Goodyear NCT's that were made for the car. I think they look fantastic and TBH I don't push the cars given they're 20+ years old now.

I had the same dilemma a few months back in anticipation of the MSA Classic run. Eventually persuaded by our local tyre bod (big on rallying & knows his stuff) I fitted Pirelli P7's rated to 150 mph (225 on the rear though, couldn't get 235). They look ok, the transformation in handling & grip over my 20 year old NCT's was unbelievable. Thrashing around MIRA & Silverstone proved wise choice, the grip & balance being, well, quite frankly, eyeball wrenching neck twisting amazing. Pretty good in the wet too (ie they grip, unlike the old NCT's).

The tyre bod was actually a bit shocked when he worked out the age of the tyres (via a code somewhere), 5 - 6 years is the max then the compounds go off.

:hrhr:

There is no doubt that 20 years for a tire is just too much.

For a powerful rear wheel driven turbo car those are not save to drive anymore, especially on wet where the vehicle is already critical on new tires. It's just jeopardising the future of the car and yourself.

I agree it's a pity Goodyear doesn't make the original spec NCT anymore, but Lotus has made some ride and handling tests on tires still available and have approved some.

I'd certainly go for these if you want to come close to the original performance.

Cheers

After putting if off and off, I finally got round to replacing the tyres this summer.

Local specialists could still get Pirelli P600s in the original size for the rears and P6000s on the front.

Haven't really pushed it yet but the feel of the car is transformed and grip in the wet is much better. Interestingly, comfort is increased also with the car feeling more composed over rough surfaces.

Moral is...get rid of those old tyres as soon as you can.

Cheers

What size did you find of each one?

Looking in the states to replaced my oversized wheels and tires. Have a set of BBS in route.

Thanks

hi guys

i have also being doing some research on tyres.in a nutshell,you are correct that the tyres lifespan is approx 5 years.i am lead to beleive that bf goodrich are making or have made 235/60/15's as my local supplier has booked some for me.furthermore the ideal is to have a matching set front and rear.it would also be advisable to stick to the 195's on the front as going bigger may give a substantial oversteer

i will let all know when these tyres arrive

cheers

Hi

Richard, you mentioned the matching front and rear tires - Indeed it is very essential for the vehicle's handling performance to have the right front and rear tires. You want to get the vehicle's understeer gradient right.

It's not only about size, you need the right force and moment characteristics from the front and from the rear tire construction.

As Lotus themselves have tested and recommended some new tires for the Esprit I'd certainly go for those if you can get them.

Cheers

Marc

think this is an excellent resource on tire technology

Marc.. All the math in the world is no substitute for real world testing.. all very interesting stuff mind you.

Les.. I can say for certain that the Nitto/BFG combination is bar-none the best dry tire you can put on any 15" wheel Esprit.. I dare anyone to test the limits!! I guarantee you will get scared before the tires do. My Esprit was transformed and sooo driveable at the limit! Jan

Jan: Have you fitted those wide tyres on to the original rims or have you changed for wider rims?

Ahh a fellow norskie... I am originally from Bergen.. good to hear from you.

The tires are on original width wheels.. honestly the rears are a bit wider and taller than I would prefer, but they still fit well and look good.

Here is a pic of my girlfriends lowered 88 wearing them.. same wheel sizes (I dont have a pic with them on my 85 but its very similar)

so how much taller are the rear nitto's compare to the stock 235/60 NCT's ? from what i remember the S3 rears are already lot taller than the S2 and S1's

cheers

They are about 1/2" less diameter than the 235/60 (25.75 vs 26.2inches) For me a 255 at 25.2 would be perfect.. Mind you the 555R do look like they mean business.. and they do deliver!

my S3 has 195/60/15`s Goodyear NCT 5`s on the front and on the rear i`m running on 235/60/15 Pirrelli P600`s (my De Lorean B) has the same tyre size on the back and is on P600 too).

good tyres and the P600 `s are sooo much better than the old 1980 style NCT`s :animier:
