Can someone answer the second part of my question please.....do you use the exact same size and spec or can you change for example 18 x 225 x 40 to 18 x 225 x 45 or to 215
Thanks
They recommend a MAXIMUM of +/- 2.5% difference

Seems so early to be talking winter tyres but I'll need two at some point but don't know whether to go for:
Toyo Snowprox S953 in for £100 delivered, thought that was a very good price.
Goodyear Ultragrip Performance 2's for £125 delivered. (these were outstanding on the snow and come above the Conti's for snow performance)
Goodyear Ultragrip 8 Performance for £130 delivered... newer than above... and impressed with Goodyear tyres, AS2's and the above. (Probably go wtih these)
Continental Winter Contacts 830P (can't find the 850 in this dimension) most expensive at £137 ea delivered.
Quite tempted by the Toyo's as I could almost get a third tyre over the cost of two conti's... anyone tried them? Probably go with the UG8P's though.
What's quite interesting is that the winter tyre tests at 225/40/18 rate the Goodyears above all others, even the Continentals.
