New Alloys/tyres

[darkninja462]

Hello all,

I am coming up to needing new tyres on all four wheels before the winter (1.6 Zetec 2003 Plate) so I come to the dilemma only had the car 6 months so thinking do I replace all the tyres or get alloys and new tyres :D as no point replacing tyres to then buy alloys in 12/18months. So I am looking for the ST170 alloys for the MK1 Focus ST, will these be a straight swap will I need to go to the garage to get speedo re-synced I am currently on 195/60/R15's and I think these are 215/40/R17's what do will I need to put on the ST alloys, is it just to get as close to current setup as possible?

there's only 1.85% out on rolling radius so fine, you taking at 60 mph 1 mph out.

you would also loose 5.6 mm on ride height but get and extra 5.6 mm of arch gap.

But winter salt will kill your alloys unless you wash them all the time.

So I will loose 1 mph, at 60mph will actually be doing 59mph? not gaining? just want to make sure :)

And surly that applies to all alloys not just the ST170 ones?

and yes any alloys, a lot keep nice wheels for summer and steels or old alloys for winter

That's a relief with speed thing, will just have to source alloys now.
