Tyres on RS250 for track and road

I paid 105 each for mine in 235/35/19. eBay username: bankofe.b.a.y

 

First time I used them in the dry I wasn't impressed but have been since.
They've logged some excellent grip and done some very competitive times.

 

Hi Mark
I have 18x8.5's TD 1.3's on my 225, i ran 225-40-18 595 rsr's on them and killed the front tyres in two track days, the inside edge just wore away i think they were to narrow on those rims, i am now running 255-35-18's and they are wearing evenly across the whole tyre.

 

On track they feel great, well pleased with the outcome although it felt a little strange on the road to start with tram-lining and i thought the tracking was out, but on the drive back from Spa it now feels normal, just needed to get used to them

 

I am not sure if lap times would be better, i would have thought so, it feels much better so that's okay for me.
My best lap at Spa was 3,06 don't know if that good never been there before

 

Really interesting thread this..

I am off to the ring soon, out of interest what tyre pressures would you recommend?

Ill be on 888s if its dry..

 

2.2 bar when hot then tune from there

Front and back?
It's strange as on the sticker on the door it has a 5lb psi difference ?
I recently did brands and the rear felt alive to say the least. Perhaps that's the reason..

 

It's only a starting point and it's easy to tune especially if you have a pump/compressor.

It's useful to figure out how much your tyre pressure rises and falls from hot to cold. This way you can set a cold pressure in confidence that it will be cold+x when hot.

My Cup2s rose by 0.3bar from cold to hot.

Get a pen, book, pressure gauge and pump and go do some motorsport engineering [emoji3]

Just found in an supplement to the handbook it says 2 bar on the front and 2.1 bar on the rears..

Ns2r been really good on my cup250 on track and road plus reasonable to buy! Much better in comparison to toyo t1s use in autumn winter

 

Thanks for the replies, unfortunately I dont have a in car tyre monitor..

 

Thank you for your advise but what pressures should I start from 32 all round or 2bar on the front 2.1 on the rears?

 

So much depends on how much heat you will get into them. Suck it and see.

 

I get that but where should I start from? In my WR1 I'd start from 28psi all round but I've never driven a megane before.

 

I bought a set of four Nankang NS2R's in 225/40/18 for £340 suuplied and fitted January 31st and the fronts are now dead, Ive only done one trackday which was Curborough and it was a sprint day. Just ordered two Yoko AD08R's for £200 delivered ready for cadwell next wednesday. Wish I went with them in the first place as I do think and have noticed the softer NS2R's wear very quick. Good tyre for the money though.

 

Start from the pressure on your door sticker. Do a hand full of good laps and check them when hot, adjust from there to keep them about the same.

You can adjust them more if you feel you need to but really you're just wanting to make sure you wear them evenly and don't rip them off the rims.

 

Cheers Jamie, I'll be using 888s only standard suspension though..

 

Thats the trouble I do know it reasonably well. lol
Youll know what I mean .

 

hi Jamie, is that 32 all round? i am running r888r and ad08 next week and the geo is very sorted with a lot of camber and has bilstein 14s. or would you suggest dropping to around 30 all round for nice hot tyres. is the 250 next week

 

have you run trefeos as i might put them on as well to try them....similar pressures do you think?

 

I've got yoko v105 on at mo but rear toyo t1s getting low on tread would I be ok to use yoko ado8 in conjunction with v105. Would you have ado8 on front or rear with the v105

 

Cheers Jamie
