Hi all, had a shiny new set of Toyo Proxi T1s fitted to my MGF.
After discovering they had fitted them to the wrong corners and correcting tyre pressures it feels very odd.

Pressures 28 all round, which was what i always used, the back end just feels like its about to let go.
Old tyres were same make, model and size. Felt fine until the new ones were fitted. Only done about 150 miles since fitting, maybe need a few more miles? Just feels wrong, much like my other one did on 'Nackering Ditch Finder Turbo Extremes' which the Mrs span and smacked into the wall.
Is it just the full depth tread making it feels loose? Not had tracking checked yet but this was an instant change.

To be honest it feels scary.

Ideas?

Steve,
the tyre fitting place should have told you to take it easy on the new tyres for about 100 miles but 200 miles if wet also that the wheel nuts torque should be checked after the first 30-50 miles

was the 28psi you used to put in correct for the vehicle? - have a look at the label on the car or in your (Driver's) Owners Manual for manufacturer's specification as many recommendations from other owners tends to be for their personal opinion used on their car with its suspension set up that may not be standard factory set up

I'm not say 28psi is wrong as I don't know

you had new tyres could they perhaps be highlighting issues elsewhere such as worn suspension bushes, dampers, springs, etc.

yes get tracking checked as if it's wrong it could prematurely wear parts of your front tyres out causing the need to change them well before time

As Trophy says, there is a known issue with tyres manufactured in Malaysia.
Was told by Toyo last week (via a tyre dealer) that they had changed the pattern in Malaysia, but were awaiting a date for production to re-start.
I went for Falken 914's which are also approved by MG SIAC, but having issues with the car at the moment, so not had a chance to drive it yet.

Many years ago, early 80's probably, I had a new set of tyres fitted to an Allegro 1750 Sport (those now sniggering should shut it unless they have driven one !) and they felt 'wrong' just like the OP's.

I went back to the shop and the area manager happened to be there and volunteered to take a drive with me.

I gave it the works and he said nothing until we got back where his first comment was 'you haven't got the wrong tyres - you've got the wrong car !' and then offered to swap the tyres for something else.

Far too long ago now to remember what they were.

I'll shall have a look at this, surely if there is an issue Toyo should be recalling and fitting for free?
All the suspension joints were replaced recently, there have been no prior issues with the handling at all, all spins have been down to me being silly.

If the tyres all match will have to do a few more mile and see if anything changes.

A friend dealt with Toyo direct and they sorted the issue for her.
Not sure what the course of action was, but I know the action was by Toyo rather than the tyre dealer.
Toyo are usually a good Tyre and suited well to the car.

The car was fitted with them when i got it and had no issues, everyone seems to recommend them and even better they are cheap! Hopefully get home before it gets dark / snowy and have a look. This was a full set of brand new tyres from a well known supplier.

Ok fair enough, but I would look closely at the place of manufacture.
Its possible that they were not aware of this.
Maybe sitting in a warehouse, new Malaysian stock arrives, gets added to Japanese, who would think to check unless they knew.
I paid 154 for a pair of Falken 914's last week, so if they offer you a complete changes, could be worth a look.

Steve, apart from the 'Made in X' on the side wall of the tyre it will have the date of manufacture in a four digit code, first two, week of year and last two year

see DOT codes near top of this page - http://www.carbibles.com/tyre_bible.html

Well had a look and they are Malasian all round.
Maybe need to bed in a bit? I imagine the cold roads means it would take longer?

If they are harder than the Jap ones should the tyre pressure be lower?
Lots of 'advice' on the interweb. 28 all round seemed to work well before.

What does everyone else use?

PS they were well under £200 all in, Halfords web special. Nobody else was close. Was very surprised.

If anything, the walls are softer.
I was advised when I posted about mine to give it a couple of hundred miles to bed in.

So what pressures do you use? 15" wheels on mine btw.
I guess if the walls are softer then up the pressure? Spec is the same though. Side walls I'm led to believe is they key factor on mid engined cars.

I always stuck to 28 psi, but tbh, I would be inclined to join the mg forum, which is where I get most of my advice from.

if you mean £200 for four that sounds very cheap (or possibly good value)

increasing the pressure on these tyres may not help for general use and at this time of the year, it does depend on a number of factors though, if you have the pressure too high you might find it makes them worse

you're right that the tyres might take longer to 'bed-in', 'summer' tyres' performance drops off at around (+)10C
