Wait... You're running cheapo non-RTFs on the rear, which haven't warn in and mixed with RFTs on the front and your complaining about handeling...?? well what do you expect?

ditch the RTFs in the front, ditch the cheapo tyres on the rear and get a set of decent non-RFTs. drive them for a few hundred miles and then see what you think. I'm sure you'll be happy with them.

the original non-rtfs on it were vredestein, which whilst not Falkans, which I thought were supposed to be ok?
They were the ones that made the car feel very wobbly.

I've stuck on the budgets now, and tbh, even without them being scrubbed in, they feel MUCH better than the vredesteins did.

It's not handling I'm moaning about, but more the the shite feeling coming from the rear whilst accellerating hard out of a bend - It felt almost as if the tyres were flexing sideways.

once they're scrubbed in, I'm sure I'll find out how well they handle.

Has anyone tried non-rft RE050's ever?

I wonder if they are actually any good?!

Hmmm

Since i got rid of my run-shi*s i have had so much more grip both in the dry & wet !

Hmmm, I'm tempted by RE050A non-RFT in the future... they were rated pretty well in the Evo tyre test this month all said and done!

They are more summer biased, but I can just get some dedicated winter tyres on 17" for the snow hehe (watch it, I'll get some 17's and winter tyres and it won't snow for the next few years haha!)

Well if you're running mixed tyres front to rear you can stay in front of me tomorrow where I can watch any spin, not feel it from behind oke:

I see it mentioned above but on the non RFT's you have the pressure too high. Try dropping it a bit. 33r 30 fr is about where people are on non rft's.

I switched from RFT to Vreds (all 4 corners) about 3 months ago and was in a similar position - car felt awfull. Hoped it was just the new tyre coating and it would scrub in. ... After about 400 miles really seemed to be bed in. Now the car sticks brilliantly.

Interrestingly the Vredestein website recomends to run at 45psi front and 41 psi rear (for 18 inch). This seems way too high and so I run about 41 front and 37 rear.

Would be interrested in opinions as this is concerning for 2 reasons,
1 this is still a very high pressure
2 this recomendation has the opposite front-back varriation to standard BMW RFT in which the back has a higher pressure than the front

sk93, I've just switched to Pirelli P Zero non-RFTs and tried giving it some for the first time coming off a roundabout this morning after having only done about 50 miles on them and it felt soft and squirmed like you mention. After another 200 odd miles today and some turning the traction control off and pulling out of a few junctions enthusiastically to scrub them in they're feeling better already

I'm glad others are feeling the same.

i had my hand forced to fitting Pilot sport 2's while i was stuck in france and they have been awful.

its not just the responsiveness of them, they really are lacking alot of grip, previously i had been able to take a long sweeping corner at upto 120 without the TC fussing but i'm now finding that its flashing at 80 and really trying to step out over 100. on my private airfield of course.

i was just at a local tyre place getting the tracking checked after hitting a rock on a DC and i got offered some fronts for £100 per side, bargin!

will have to take the car for a drive later to see how it responds with the same tyres front and back, i also got the rear pressure lowered to 33psi.

There was some debate about this a while back so I called Vredestein direct - they told me to ignore the web site (these were the absolute maximum pressures) and to run them at BMW's highest recommended pressure... I was running 33/36 (front/rear) but have just dropped to 30/33. The former are the max 3.0 pressures, the latter the 2.5 pressures... I decided to drop after a post from Ed, who's run Vreds before on his much loved Vauxhall ( oke: ) and knows a thing or two about cars.

EDIT: Sorry Sk93, thread has drifted off topic again!

ran non rft on the rear first as they needed changing and noticed the usual amazing difference, didn't notice that much more when switched to non rfts on the front when the old on'es ran out
