Thanks hmi, I'm very near hounslow. Might also try Feltham tyre centre too.

Anyone gone for larger size's in 19", what pressure is recommended?

235/35/19 front - 265/30/19 rear

For the "plus one" fitment (ie 235/265) - 36-37psi front, 38-39psi rear, depending on how you like your setup. I'm currently 37psi front, 38.5psi rear, and it works very well as a balanced ride/handling setup

Thanks E92 fan, having Goodyear Eagle F1 assims fitted in the morning at last I have made up my mind, Hounslow tyre center, good price around 680 all in.

I presume the tyre pressure is for any brand of 235/35/19 265/30/19 ?

[hmi1750]

I have those tyres, but on 18". No complaints.

[dazzapb]

Thanks for the advice HMI, great setup - hounslow tyre centre.

Great price and got a cheap hunter alingment done. Some guy was there with a 2 day old fiat 100 hp, as the steering was out a mile!

Fitted the larger size 19" Goodyear eagle F1 assims.

WOW WOW WOW, what a difference in road noise, bumps etc. Managed to fit (just) the old RE050as into the car and are in the garage ready to put back on come trade in time.

Got 2 cans of holt weld. Loving non RFT's!!!

Can someone (tony) pls double confirm the pressures, as I don't have PS2's? and have the larger size, 235/35/19 265/30/19

Checked them and they were set at 32 psi, which no doubt is wrong!

[dxb335d]

I am in need of rears. Can i go 265 wide on them whilst still running 225 at the front.

[hmi1750]

32psi is too low... Gizze recommends using 4psi below recommended (on the door) for the RFTs.

I run my non-RFTs 18" on 38PSI which is too high.. so I will tone it down a bit.

You might want to try 36psi front and 37psi back... or 38front and 39back (not more as then its too bumpy and will prob wear in the centre more)

I had the hunter alignment done too.. it did the trick, but I would like to go the full hog sometime next yr (if I keep the car).

Yup - try 37psi at the front, and 38.5psi at the rear to start off with. That should give a good balance between handling and ride comfort.

cheers hmi and tony

At 36 at front and 38.5 at rear. can't believe the difference between RFT and non RFT.

just been for a blast down the m3 at 70mph of course, one thing I notice is that the streering feels very light, almost wallowy, its like movement of the wheel left and right is light for about 3cm of travel.

It feels fine, but alien, is this my pressures or just the move to non-rft?

Tone if I want to go for comfort, whats the lowest PSI I can go?

You're pretty much at the lower limit at 36psi. The slight imprecision you feel around the straight ahead is down to the fact that a) you're on new tyres, so they need a little scrubbing in, b) they have a different, less "edgy" feel than the old Bridgestones, and c) you're at 36psi on the front

If you go up to 37psi, you lose a smidgen of front-end compliance, but gain a fair bit in straight-ahead precision. For me, I'd run at 37psi and suffer the minimal loss in compliance.


The rears are about right at 38.5psi - I wouldn't go any lower than 37psi personally, as I find that gives a reduction in straight-line stability at higher speeds...

Crikey does 1psi really make that much difference

Yes - fine Carlos. This is the setup that I have. If anything, logic would tell you that the car will have more traction at the rear and have more of a tendancy for understeer, but I haven't noticed this really.

[gIzzE]

One thing worth mentioning is the EVO test was done in a Golf.
Completely pointless test imho as the GDS3 is a great tyre on FWD and AWD cars and stinks on BMWs.

Absolutely agree on the fact that the test should be taken with a pinch of salt - tyres that work well on a FWD Golf, will not necessarily give the same results when on a RWD car or a 4WD car.

[hmi1750]

I guess next time I will try the PS2s and see how they compare.. I will need rear tyres sometime next yr I reckon.

I think it was the assym F1 not GDS3?

Yeah it was.

Sorry, what I was trying to say was, the GDS3 always gets great reviews when tested on Audi and VW's etc. but the guys with powerful RWD cars never like it as much as say the PS2.

So that EVO test was great if you owned a Golf but not much cop if you own anything else.
Would have been nice to have seen the test done with say an M3 as well, I bet the results for each would have been completely different.

In a Golf or Audi you are looking for ultimate grip, where as most people in a powerful BMW are looking for a tyre that is progressive in the way it lets go so you can keep control of your car.

I never saw the appeal of PS2's with any Audi I owned, in fact had a few BMW's and still didn't see the appeal, it wasn't until I had the M3 that I realised just what all the fuss was about, if you have a powerful, RWD and well balanced car I really do beleive they are in a league of one.

[dazzapb]

nice points Gizze, I went for the F1's purley as I got a good deal (larger size) 235/35/19 and 265/30/19 for 680 all in. Maybe in hindsight I should of paid the extra 300 to get the PS's, but I couldn't warrant the extra expense. (in other words the misses wouldn't let me

I don't drive fast (around corners) as I am crap at controlling oversteer anyway

Got 4 bridgestones in the Garage now, waiting to be put back on come trade in time

the only thing I don't like is that the tyres once on the rim are flush! no rim protector or anything, its as straight as a die and looks boring!

[DaveC]

I run 34 fronts 36 rear on my 17" Non RFTs - currently have 36 and 38 in and its too firm and no more precise and the back is skipping a little rather than riding - for my car and tyres 34 & 36 seems to be the sweet spot.

Other peoples advice on tyre pressures is a bit useless except for getting a starting point - unless its the same tyres and the same wheels you may not want the same pressures. Add to that the personal preference thing and really it's best to just experiment... anything between 28 and 40 isn't going to be dangerous so experiment.
