What idiot put those size rears with stock fronts? If you take a tape measure to them, the diameter of the rears compared to the fronts will be about 20mm less.

Ahhh it is starting to make sense now

Tyres are Michelin pilot super sports which I have been told are quiet good tyres

It's a shame as all 4 tyres are not far off brand new lol

What would you recommend changing the fronts to accommodate the rears or change the rears to OEM size?
I would recommend selling the MPSS and buying a set of stock Dunlop or preferably Bridgestone runflats, they're night and day better, but everyone here will disagree with me haha.

Don't dismiss them until you have tried them is all I can say :)

You're not wrong, but not 100% correct either :chuckle:

A set of Dunlops are more expensive than a set of MPSSs to begin with. MPSSs do last longer (7000mls vs 12-15000mls).
The dry grip of the dunlops (once hot) on track is way better than MPSSs, but once the dunlops get to 3mm, in any condition they get really bad, tramlining, traction (with halfthrottle etc).

A fresh set of dunlops are great, but MPSSs are still very good even at 3mm tread.

The Bridgie run flats are loads better that MPSS! although I'm interested to try the 4S tyres.
The MPSS bounce like a fat blokes moobs on a trampoline, they are shit lol

foooook MPSS (Michelin Pilot Super Sport), they are old hat!! haha. MPS4S (Michelin Pilot Sport 4S) is where its at, apparently!

They are the new replacement tyre by Michelin, to replace MPSS.

They sound like mpss, but with stiffer sidewall (less high speed bounce) = WIN!

But he already has MPSSs, just needs a pair front or rear to get it back into shape, cheapest option would be to get some 275 fronts..
Then once all the AWD errors have been given a green light, worry about MPS4S/R888R/Cup2s/Dunlops etc. ;)

Thanks for the advice guys

Will get these swapped over and hopefully it will cure the problem

Not sure which tyres to go for yet I will do some more research

All the research in the world won't help you, it's a matter of feel, so has to be experienced and judged by yourself.

OP don't listen to the tyre war factions!

Just get yourself some 275 MPSS up front for now and they'll see out the winter for you and hopefully let you regain some confidence in the car once all the warnings go away.

Worry about what tyres to have later

Yeah I think 275 MPSS will be the easisest way for now and worry about tyres on their next change..... touch wood it will clear all the lights

305/30 is 27.3 inches tall
255/40 is 28 inches tall
275/35 is 27.6 inches tall
265/35 is 27.2 inches tall

Hi guys.....

Changed the tyres to 275-35-20 on the front to match the 305-30-20 on the back and the car is still bringing up all the lights the same as before ***128532;

Anyone else have any ideas to what it could be?

Okay. You've done the right thing by having the correct tyre sizes front and rear.

That eliminates the easy fix.

Now I'd suggest you step away from an Internet forum and book your car in with a specialist to work through the errors.

A proper specialist will sort it quickly for you.

Hi guys,

Have recently just brought a R35 Black edition 2009 and have owned the car just over two weeks and keep having issues when I am putting my foot down.
Have searched for through a few of the posts as I have seen a few people with the same problem but just querying whether anyone has any other ideas to what it could be.

Basically when you put your foot down and get round the rev counter every now and again all the warning lights come up and the car jolts. Lights are ESP, ABS, Handbrake light and 4wd lights all come up on the dash. If you turn the car off and on again it resets itself and doesn't do it unless you put your foot down again.

Using me ECUTEK I managed to get the following fault codes:

C1162 - Park break switch #2 released circuit failure
C1193 - Speed wheel sensor RF input short circuit to ground
C1105 - Traction control disable lamp circuit short to battery
C1115 - ABS power relay output short circuit to battery

Following some of the post I have read about there being issues with the negative terminal of the battery I have removed that cleaned it and put it back on nice and tight but keep getting the same results.
If anyone has any advise on what it could be I would rather try a few simple things first before I have to weigh out loads of money 2 weeks after buying the car.

Appreciate and responses guys
Hi, I know your post is a little old. I just wanted to know if you managed to sort the problem and how.? As I am having the same issue, I’ve had the car for almost a year (65 plate) this issue started after taking it to litchfield for a major service.! When driving normal nothing happens but when I push the car I’m getting some sort of a lag as if something is holding the power down and letting go all of a sudden, and sometimes I do get my ESP light coming on.
