What size tyre.. details inside.

Okay so I've bought new wheels. Im working on the premise that my fronts can fit my old rear tyres (same width at 255 and same circumfrence fitted and at the same pressure sat side by side.) My existing tyres on the new wheels are stretched. I dont want too keepnthis stretch (255 on a 12j!)

 

Im looking too retain the same or close enough to not matter circumfrence on my rears as were on before with little to no stretch. Ive got 255 35 18 on atm. Wheels came with 265 35 18s. Im looking at mickey thompson et streets that are 315 35 18.. im not sure how much taller these would be. Would it be an acceptable amount of difference or should i look at others? I dont mind a slight stretch but not that much. Anyone whos fitted 12j and done similar can you please give me advicw and pictures of fitted tyres and an idea of how good they are in the wet please.

 

If im better off looking at a different width or depth tyre please help. Ive done the tyre circumfrence maths and got a 24.52 too a 25.02 with the 265 too 315.

 

Ill give proper maths later this evening. Cheers

So:

 

255 35 18 I have on at present has a standing height of 25.02 inches

 

My old 265 35 18 has a standing height of 25.3 inches

 

The mickey thompson im looking at is a 315 35 18 the standing height is 26.68 inches.

 

In mm the old tyre is 642.62mm the new tyre is 677.6mm

 

This works out about 4.5% difference in the height. Would that be okay to run? How much difference would it make too the speedometer? Would a 30 depth tyre be better? Can i get advice on a suitable tyre?

 

Is this too much? Could I compensateor adjust things too suit?
