Lotus Elise S2 Bridgestone Tyre Presure

[cjwjames]

I currently Run the OE Bridgestone on my S2 ( I think DeanB also does the same) what is the general consensus on tyre pressure do you run them at manufacturers specified PSI. or slightly under to give a better grip ?

[DeanB]

I run mine at 24 front 26 rear - operating temperature though, not cold. On a track day I might go a bit lower, always measuring when hot.

I read i should run them 26F 29R is this standard pressure? I don't know much yet as i have only just had the car. It feels alot better than the 31psi l around which it previously was anyway!

[Gary ZBJ]

26f 29r is too high 23f 25r is what i used to run mine at

If they are LTS bridgestones it might be worth thinking of some new tyres, they have not been made in a long time so could be quite old

Ok Gary I will drop the pressures tonight thanks

[Gary ZBJ]

No problem,

Whilst you are adjusting the pressure have a look at the date code on the tyre, is 4 digits indicating month and year of manufacture.

There is much debate over how old you can let the tyre get before performance drops, but at least you will have an idea of the age

Secondly, if they are the tyres specific for Lotus, they will have LTS after where is says RE040. Again, loads of people get on fine with none LTS tyres, but you will know what is on the car

Apologies if stating something you already know.

No problem i didnt know about the LTS, . Had some bone hards tyres on a Civic type R once and it was horrible, they had gone off because of age.

 

My tyres look (and feel) pretty brand new but i will check the dates. Thanks for the info

I think Bridgestone stopped making RE040 at least five years ago.

The manual says 26 front 27.5 rear.

 

One of my non-LTS tyres has 4211 as the date code. I presume that means week 42 of 2011.

[Gary ZBJ]

Yeah, manual states higher than I was advised by Steve Guglielmi to run mine at, I always ran them at 25r / 23f and was happy with them, no adverse treadwear.

Yeah, 4211 will be week 42 of 2011.

The temperature stated in the manual works well, but some people say it gives uneven tyre wear (centre of tyre wearing more). I run standard temperatures and get pretty even wear, with track days taking more tread off the edges of the tyre to even things out. Ymmv.
