Hi everyone.

Had my rear tyres replaced 2 days ago due to the ones that were already on (GY NCT5) looking like 50 pence pieces and having a nail in one of them. They have been replaced with GY F1s, but the back end seems a bit twitchy when cornering, there also feels like the body is rolling more too! Is this just a case of needing to give them time to bed in??

Give them a chance to scrub in mate.

Re-torque your wheels in a couple of days and check tyre pressure at the same time as well.

I'm sure they are/will be fine.

Ta for the reply steve. Its quite shocking how much different it drives at the moment, feels like the ARB has snapped!!

How many miles...... lwess 100-200 and they won't be scrubbed in and so the rear may feel like its sliding a bit.

I found the F1 GSD3s were bad for that feeling, vene mroe so than the F1 Asyms which I jad fitted about 4 weeks ago, but now I;ve done anot 1000 miles there are bedding in nicely and feel well planted.

Also, if your FWD, then whack em on the front where you want most grip.

I experienced exactly the same handling/roll problems when I was running GY F1's.  I've got Michelin Exalto's now, and I'm really happy with them.

You could not be more wrong the rears are the unloaded tyres 99.9% of the time you want the most grip there which equals once bed in the ones with most tread especially in the wet !!

Give it time fella they will bed in but as had been said the design gives a less direct feel due to the movement in design and structure, on the road it can actually be a benefit as it normallt broadcasts the limit of grip earlier and gives you more notice on breakaway etc, Falken FK452's are a great little tyre for no money with very stiff sidewalls if you fnacy a change !!

Yup, less that 100 miles even (have not been driving much recently... for a change)! Guess ill have to give them chance to scrub in!!

Thanks guys!!

Completely disagree, grip where the power is.... have mates who work in motor industy/sport and they always advocate grip where the power is.   I totally undrestand what you are saying about the rear being unloaded and requiring grip but you should never sacrafice grip at the driving end, especially on this wet-weather country we live.

You can argue that if the fronts are relatively new then yes, pop the new ones on the back but given that 4mm tread gives nothing like the grip or water dispersion of 8mm and 3mm is something like 20% as effective as 8mm, then it stands to reason that its better to have the grip where the power is being delivered and at the end which is doing the turning in FWD.  Doesn't necessarily apply to RWD or 4WD under the same logic.

The other side of the debate, apart from your reason, is that new tyres drive different than old, so its better to retain the older ones on the front as they'll feels the same and put new ones on the back.... sensible logic as well, but many motorists don't understand the degrading performance properties oif tyres and would end up putting tyres with 2-3mm on the front (from rear) with potentially dodgy consequences!!

Also, rotate tyres so they wear evenly and then replace all 4 at the same time!  Anyway, have seen boths side o0f this debate many times and my resolution is 4WD!!

Difference of opinion I guess

:)

I totally agree with Six Degrees,

I always have the better rubber on the front of my car, not the back.  The front wheels do all the work and also hit water on the road first.  I'd sooner have the good rubber doing that for me and the more worn stuff on the back.  I know the arguement is that rear end skids are harder to control, but I'd still rather have the better rubber working for me the 99.99999% of the time, rather than a 'just in case' situation.
