difference size tyres front and rear
 

Of the subaru chat, but is it ok to run the same size tyre on the same axel but different size front and back ie fronts 175x70 rear 185x65.

your thoughts please:thumb:

The change in aspect ratio might upset the centre diff as the wheels will be turning at different speeds.

No mate def not. ( Here is what Subaru say ) All 4 tires must be the same in terms of manufacturer, brand tread pattern construction degree of wear speed symbol load index and size, mixing tires of different types and degrees of wear can result in damage to the transmission.

think there's a missunderstanding i mentioned off subaru chat its on my daily driver an astra 1.6

Oh sorry, thought you was talking Subaru :)

FWD doesn't matter. No centre diff to wind up!

I have 175x70 tyres on the front and some came up cheap and brand new for the rear 180x65 so have fitted these surley it should'nt make much difference on a fwd car as its only dragging the rear's behind it

Legally the wider tyres must be at the rear.

dunx

Unless you are cornering or are braking to the point where the front's provide more grip than the rear's, then you are spinning. As dunx says, wider tyres for the back. You always want more grip at the rear.

I was all psyched up to say NOOOO but you're on about a FWD car bah......

My mate did on his vectra years ago and kept getting warning lights on the dash, abs I think it was.

yeh bigger ones are on the rear ,felt fine today on my 100 mile daily commute to work job well done.

I knew someone would have ago about mixing tyres def nono on the scoob but wished i had got 185x65 allround really good tyre SAVA i think they call them.

Thanks for the input guys !!!!!
