Hi all,
I have budget tyres all round on my Sonic, and when pushed, it is always the rear end that steps out, never the front at all, probably to be expected given the weight of the engine at the rear.
Do you think there would be any benefit in putting some more expensive softer/stickier tyres on the rear only, to try and balance the grip and help out the rear end.
Just a thought.
What do people think?
Jonathan.

Personally I would nevery have a mix match of tyres on a car.
Toyo T1R's cost about £150 for 4 and are considered to be
One of the best track/road tyres around.
Or if money isn't an option then toyo R888's for around £500
Depending on tyre size.

I'm about to put Dunlop DZ03G soft on my Rocket for exactly the same reason, although more so for events than every day driving.
I thought about rear only but decided it was not a good idea.

It makes perfect sense to mix tyres, one end has more grip than the other so try to correct the imbalance, but never mix on the same axle. Different compounds/tread patterns from front to rear could catch you out though. Image rain with a set of slicks on the rear and all terrain on the front for a worst case scenario. Take a Porsche for example, the one with the engine on the wrong side of the rear axle! It's quite common to see them booted with 205's front and 255's on the rear. Guess they have to do something to try and get the car around corners  Take a Smart car, 145 R15 front and 215 R16 on the rear, very common. The manufacturer spec is 23 psi in the front "bike tyres" and 36 in the back presumably to carry hefty load of that 660cc engine! So I would suggest tyre size and pressures are the way to experiment, mixing compounds/makes/treads could create unpredictability. |

I was thinking more of issues of mixing types rather than sizes.
I am going to keep it simple though and have 205/50/R15 front and rear so they can be rotated.

It's not an issue mixing sizes between front and back I think wider tyres on the back
is a must have for this type of car, the only issue comes if you have a spare wheel in case
of a puncture what size tyre do you have on it.
I would stick with the same make on all 4 tyres.
My budget tyres are for the off as soon as I get the car back on the road, the grip
even in good weather was poor.

What is your wheel alignment like on the rear wheels?
My adjustment mechanism means I can be either slightly toe'd in or our slightly toe'd-out but not perfectly in alignment.
I have found slight toe-in (1 degree each side)to have more grip.
