Member Jonathan Kay Posted October 20, 2021 Member Share Posted October 20, 2021 There's quite a bit in the archives, but it's scattered;https://www.google.com/search?q=site:lotus7.club+ar1With a very quick search I didn't find anything on pressures...

Rusty Nuts Garage Posted October 20, 2021 Author Share Posted October 20, 2021 Cheers, will do some searching later today. For vehicles less than 800kg, Nankang recommend min pressure of 23psi, so I'll use that as a starting point. Link to comment Share on other sites More sharing options...
aerobod - near CYYC Posted October 20, 2021 Share Posted October 20, 2021 I've had to drop as low as 14PSI cold pressure on the AR-1s due to the stiff sidewalls (for the car weight). That is likely 19PSI on track, but is typically 17PSI after a cool down lap before I can get out the car to measure it. Link to comment Share on other sites More sharing options...
SM25T Posted October 20, 2021 Share Posted October 20, 2021 23psi sounds too high Link to comment Share on other sites More sharing options...
K7 VCT Posted October 20, 2021 Share Posted October 20, 2021 18psi for my nankang ns2r 1856013 is ok. Just for reference Link to comment Share on other sites More sharing options...
Area Representative Golf Juliet Tango Posted October 20, 2021 Area Representative Share Posted October 20, 2021 If checking pressure cold, I wouldn't go over 20psi ever. Link to comment Share on other sites More sharing options...
Rusty Nuts Garage Posted October 20, 2021 Author Share Posted October 20, 2021 Thanks - It certainly does, I'll try 19 and take it for a run.. Link to comment Share on other sites More sharing options...
Rusty Nuts Garage Posted October 20, 2021 Author Share Posted October 20, 2021 Thanks, yes, that seems more reasonable! Link to comment Share on other sites More sharing options...

22daz Posted October 23, 2021 Share Posted October 23, 2021 I had a mate weigh some of these for me who is a tyre retailer. Whilst the actual weight slips my mind I do remember thinking there's not a chance I'd put them on my car. Very heavy for a seven. Link to comment Share on other sites More sharing options...
