I fyou can afford them, go for the 195/40/16 as the tyre wall looks soooo much thinner than the 195/45/16. However, u can pickup 195/45 for around £30-£40 per corner these days, so its whatever you can afford.

^^ You can check out how much your speedo will be affected using that.

Ive got a set of four Fulda 195/45/16's for sale - they are about £48 each on mytires.

I'll do them for £35 each inc postage.

yeha i got mine from mytyres, ive got toyo proxes, but wish i had paid the extra 30 or 40 quid for uniroyal rainsports, cos these toyos aren't very good in the wet

195/40 look prettier

Just realised that after looking at prices!!

www.mytyres.net seems the best for prices.

99% of people use 195/45 because the 40 profile ones are like 80 quid each.

you will loose acceleration anyway cos the 16's will be heavier.

I started with standard wheels and tyres. I have 195/45/15 tyres on my 15" alloys at the moment.

I am putting 16" alloys, and don't want to affect my speedo, or acceleration.
So what profile tyre do I need on my 16" alloys? 195/40/16?:boggle:
