Yokohama Parada Spec II Tyres (205/40/17) opposed to (205/45/17)

[Jaw_F430]

Does fitting 40 profile instead of 45 profile have any noticeable effect on the speedo reading as the overall O.D of the tyre is smaller?

I am looking at getting a set but seems daft to pay £100 a tyre for 205/45/17 when the same tyre but 205/40/17 is £55 a tyre

This is a very useful website... Tire size calculator

Why not go for a set of 215/45 R17?

I know that Big Show 300 has got Yokohama Parada Spec 2 tyres in the 205/40-17 size on his MCS, if that's any help to you .

Yes I've seen that somwhere, was hoping he would post

At 100 speedo mph the actual mph is 94 mph on the GPS... I've had 45 profile F1's and much prefer the 40's on the Yoko's. I'm running 205/40/17 and I can't fault them at all tbh, especially at £55 a corner.

You'll love them.

Oh and if you're lowering the car to 'track' levels then stick with 205's as my 215/45/17's rubbed like mad at the back with the Cross.

I have been in Bigshows car at Bedford on these tyres and they stick beautifully. As a result I made the leap off the run flats.

If you're not lowering the car, the lower profile tyre can look a bit lost in the wheel arch on a 17" wheel.
