Dunno but Pzero 18s are still costing almost £200 :rolleyes:

I hear good things about Ultrac Sessantas, good tyres and cheaper and less noisy, probs worth a try?

£200 is going some for Neros isn't it?
:eek:

I've got a pair of Sessantas on their way for £130 each so I'll report back on those!

Should not be an issue as only a slight difference - Ask your local tyre fitter if you require confirmation, they can check clearance.

they don't do them in 235/40 r19.

the options for the TI size are:

Continental ContiSportContact3
Bridgestone Potenza RE050A
Yokohama ADVAN Sport
Pirelli P-Zero Nero

and I think some winter Contis and Dunlops

Don't forget they need to be in hefty weight rating(96Y):eek:

Event have the PZ's listed at £206.05 & the Conti SP3 for £213.77.

The B'stone RE050's are £215.92 but are a lower load rating.

OR get a bit more for less :D

On Blackcircles 245/40/19 available at 98Y rating - Dunlops at £132.54

I would go for it at a £70 or £80 saving per corner and more rubber on the road ;)

Quite. On Event, £140.66 Dunlop Sport Maxx XL 245/40/19 98Y.

Are we talking about just 1cm extra width here:confused:

What affect would it have on the steering, clearance & on already sensitive geometry of the 159:confused:

245/40/19 would be very similar o/a diameter difference (1.19%) - I can't imagine the extra 1cm width would cause any clearance issues.

I have visions of this advert from a bye-gone, non - PC age:lol:

Nah, would be fine - 10mm width additional only which is obviously only 5mm each side of rim so not going to cause an issue.

Classic clip though! :)

rather go for 245/35 r19 as they're closer in diameter to the 225/50 r17 standard tires (speedo is calibrated to that dimension too).

Fair enough but more choice at higher load rating on 245/40 and closer in diameter to 235/40.

We are talking only mm's here - less than diameter difference between a new and part worn tyre!

Never look at my speedo as I have a centrally mounted and accurate GPS Road Angel +.

If the car is set up for 235/40/19, how would 245/40/19 be more accurate that 245/35/19:confused:

all car manufacturers deliberately calibrate the speedo to indicate slightly more than the actual traveling speed. the standard car has 225/50 r17 tires so the speedo is calibrated to indicate 1-2mph more with that tire setup. 235/45r18 and 235/40r19 tires would indicate the exact speed - that would also be classified as sporty behavior by the italians :)

as the TIs only differences from the standard car are the springs/shocks I doubt they recalibrated the speedo to the TI wheel size. if they'd done that they would also declared slightly higher top speeds also. (btw, I just seen the new my08 catalogue and it seems you can order sport TI suspension on every model now for a few hundred euros).

so, 245/35r19 would be closer to the original 225/50r17 than 245/40r19. with the later you'd actually travel at a slightly higher speed than the one indicated.

SR, you can test the accuracy of your speedo with the GPS :)

btw, don't you guys use winter tires in UK?

Rolling radius is what determines speedo accuracy - The 19" is a given, the tyre wall is a percentage of its width so 235/40 tyre wall is 40% of 235mm. On calculation you will find that 245/40 is closer in tyre wall depth to 235/40 than 245/35. Make sense :D

No. We hardly get any snow worth bothering about.
