Early Elan Tyre at last

Hi

i thought you guys might like to know that at last there is a good tyre for the early Elan, from Pirelli which is the 145HR13 Cinturato CA67. untill now there has not been a suitable tyre at all nothing with the right period carcass, and nothing developed for a sports car. just buget low performance tyres. the the Cinturato is a H rated sports car tyre developed to go with cars of the '50s, '60s & 70's. which among other things is why they fitted them as OE to cars like my Elite.

I used Sasco Motorsports to get tires from England for my Elan.

I loved the Dunlop Formula -R tires, but the 185/70 mold got broken in the Kobe (?) earthquake. The 175/70 was still available.

Sasco brings in containers from England where there are more choices than here.

175-70-13 and 185-70-13 Pirellis CN36 are also available now.

Back in the 80's the hot tire was Phoenix Stahlflex 185-60-13.

My race car mechanic buddy said we were cornering at > 1 g (Spyder chassis and suspension, too) on the Dunlops. Of course, this was 20 yrs ago....

An Elan is never going to handle as well on a 70% profile tyre as they do on a proper period 155R13 (and 165HR13 for the +2) such as the Michelin XAS, which are currently by far the best.

However lots of people have changed wheels which means that the correct tyres may be uncomfortable on a wider rim. So if you are in a situation where you need to run a wider tyre, there is no doubt that the Pirelli Cinturato CN36 are by far the best 70 profile tyres for a cars like the Elan. The handling is compromised by the over sized tyre, however the derogatory effects are minimized because, the CN36 has carcass design that was developed in 1968 to compliment cars just like the Elan. Its all in the rounded shoulders of the carcass.

Do any of you guys fit 145R13 tyres?

I can't agree.

My '72 Elan Sprint used the normal tires at first. Then, I tried others.

So, I have a bit of experience with various tire sizes. Drove that car for 20 years.

When I put the 175/70 Dunlops on, it was almost a revelation.

Steering response was terrific. Grip was prodigious.

I realize that "handling" can mean different things to people, but response, transient behavior and grip were all close to amazing.

Doug, have you tried the larger sizes on Elans?

PS: I had adjustable shocks/springs on the car and Spyder suspension. Rear suspension was no longer Chapman strut, but double A-arms.

Also corner weighted car. Borrowed scales from BMW CCA NJ chapter. Engine builder was surprised at its stability. Said it was the most stable Elan he'd ever driven.
