Hi all.
I recently changed my tyres to the standard Yokohama's that are fitted to the facelifted MR2 from new. When I bought the car it had three different makes of tyres on it, including Marshall tyres!? Anyway, since I changed to the standard factory tyres the car seems to understeer more, especially in the wet, and not be quite as responsive regarding the steering. The tyre pressures are set to the handbook, and I wondered if this is indeed how the car is meant to handle, since I only really have experience with the old tyres. I know the pre-facelift car had slight understeer on turn in, so it could just be that the facelifted one does too.

Any help much appreciated. Thanks.

How many miles have these tyres done? Most, if not all, need bedding in.

Car should have mild understeer followed by oversteer if pushed harder.

I have a set of Yokohamas, my car is pre-facelift, but have never had any problems like that. Maybe I just don't drive it hard enough !

Another thing, make sure you have your spare+jack in the front (the car needs this weight) and that your wind deflectors are still there (little lips hanging down in front of the front wheels).

Everything is in place. Spare wheel, wind deflectors, etc. tyres are bedded in, I suppose they've done about 1500 - 2000 miles.

I'm not necessarily saying there is anything wrong with it, I'm just wondering if it  is meant to have some understeer as I only have some experience with the old tyres (turn in was really responsive, followed by oversteer accellerating out). I had the TTE lowering springs fitted as well, I suppose that could make a difference.

They did have a degree of understeer as standard (engineered in to try and stop people wrapping them around lampposts and earning the car a 'widowmaker' reputation) - you can trail brake quite heavily usually to point the nose in..

The whole car seems to pivot around the engine, and in such a fluid way that nailing an apex becomes instinctive. If there is understeer it is easily quelled with a slight lift of the throttle, while a heavy right foot will load the rear of the car up beautifully out of a bend. The MR2 is not a car with which you take liberties, but over time you'll relish the thrill of mastering its tail-biased balance. Roger Green knows the little Toyota well and is smitten: 'Despite having driven several thousand miles in this car I'm far from bored of it because every time you drive the MR2 you learn another facet of its character. You have to drive it, too. It demands your concentration.'
