You have 275 rear tires on the OEM 15x8” wheels? How many miles on those tires? My relatively high mileage doesn’t help.

Rear wheels:

late 88 Esprit:
Dunlop Direzza DZ101 - 245/45-17 - got 19K miles - worn to the bars
Current 87 Esprit
Dunlop Direzza DZ102 - 245/45-17 - got 6K miles and flat - appeared to have heat damage to inner driver side sidewall - evidence of bubbling.

I searched for my late 88 Esprit pictures for the driver side heat shield - it is about 1" deeper than the 87 heat shield (the top of the shock tower more visible)


My plan is to somehow extend the heatshield (either MIG-weld extension or remove and fabricate new longer shield).

The point is - larger-than-OEM tires on my 87 with the standard heat shield and 6K miles of driving (in about 3 years) may have contributed to the flat. The late 88 Esprit had far more mileage without any evidence of heat damage. In fact, I have the Dunlop Direzza DZ102 (that replaced the late 88 DZ101) on the 87 today - it replaced the newer DZ102 that went flat after 6K miles.

The current DZ102 has about 6K miles already before the late 88 got totalled.

FYI

sleekgt It’s easier/cleaner to simply extend the heat shield down. My previous 19K miles on my late 88 indicates that is sufficient to protect the tire. But it definitely doesn’t add lightness ;-)

Why not just wrap/insulate the exhaust pipe.
I plan on do so with fiberglass insulation packed in silicone textile as a blanket. (My best description)
It is widely used on large vessels diesel engines to cover all hot spots. An IMO requirement that no hot spot must be hotter than 150C.

sleekgt I made identical request for the closest to 15" OEM that is possible.

Tire request

Atwell,
I went to the Nito website, and made the request as suggested.
I need tires all around, so I hope something comes of it.
Regards, and thanks.

So you are able to squeeze P275 50R15 on a standard 8” rim?

I'm not impressed with the tread on the rear tires, basically they're street legal drag slicks. I've been told those are the only tires available that fits my car because my car has European suspension and sits lower to the ground than standard Esprits.

You didn't say which model of tire you are using, though. It's like the readily-available BFG Radial T/A: those H rated tires may not be optimal.

REMINDER:

I'm encouraging others to request the OEM sizes in a summer tire...not asking for experiences. Several times a year, owners ask what they can fit...

Some OEM sizes are not available, even in 17" sizes. If we point out a demand, the hope is that our sizes will be produced in the future!

Laser Bob I use Nitto P205 55R15 in front and P275 50R15 in rear. The rear tires usually need replacing more often than the front tires, and so far (knock on wood) I haven't had issues getting them.

Vulcan Grey I don't own the 15/16 wheels anymore, and they wouldn't fit over my brakes... and I sold my 89 brakes to Jason Miller
05-29-2019 12:17 PM
carbuff Travis, you should request the stock 15"/16" sizes for your 89. (Just in case you want to bring it back to 'stock')

That is the point of this exercise....
05-29-2019 12:12 PM
Vulcan Grey I did the V8 sizes in NT555 G2.

I already have the NT-05 on my V8 wheels

Nitto tires

Hi Folks,

Tire availability for our cars has been an issue for years.

Users of another sports car I am associated with have reported good results (and prices) from various models of Nitto tires. So, I was browsing on their website and noticed that they have a 'Request a Tire' submission area. I promptly submitted a request for a summer-spec set of 15 inch NT555 G2 in OEM Esprit sizes (235/60-15 & 195/60-15).

https://www.nittotire.com/find-a-tir...t-a-tire-size/

I thought that if many of us requested sizes that we can use, perhaps they would see a potential market niche and actually MAKE some!

All you owners out there should make your desires known, too.

The usual disclaimers apply: I am not an employee of Nitto, nor do I stand to benefit in any way...


Post back here with the requests you made. If there are similar request areas from other brands, post that here, too!
