Like many I need to change the front tyres on my CRV EX and I am considering a different brand to the ST30 Dunlops, which are the OEM tyres front new. My question is would have a different tyre type on the front and back effect the 4 wheel drive system in any way, also would it unduly effect the handling of the car in bad weather as the tyres may have different grip front to back?

I would like to try the Yokohama PA02 SPEC-X by not sure if these are all season tyre as the US reviews seem to be a little confusing. Anyone out there in the tyre trade who would know the answer?

Why?

It is on 2WD until it detects slip so I would have thought there would not be an issue with the "winding" that the Freelander suffered assuming the tyres were the same make on each actual axle and all tyres were the same size and spec.

I must admit I prefer the same tyres on all 4 wheels but that is my personal preference.

as long as the same tyres are used on the same axle you won't have any problems. this 'tosh' about having the same tyres on both axles is rubbish. believe me.

I imagine an issue will only arise if the replacement tyres are a different size than the old ones. Before you stop reading... tyres that are meant to be the same size are often slightly different. My Avon tyres are 2 mph different to my (supposedly identical) Continentals.

If the size difference is big enough to cause the hydraulic pressure difference to activate the 4WD valve, then you will have a problem.

only if the tyre size is 'slightly' different on the 'same axle'.:)

No, I think the size difference is important if it's between the two axles.

If there is a difference between front axle speed and rear axle speed, then the 4WD is engaged.

True, but I don't think its 'that' sensitive. A mainly front drive, diesel engined (heavy nose) vehicle will generally wear out front tyres a lot quicker, my Accord got through nearly 3 sets per rear set. The system has to cope with often new tyres front and nearly worn rear without unnecessary engagement. I doubt if the marginal difference between brands is an issue either.

The strange thing with the Honda system is I can wheel spin the front tyres considerably without the rears doing much but go on snow and the rears kick in quickly it feels like an electronic system but its not! (our other car has electronic 4WD drive)

thanks sillygoose. a brand new set of fronts and fairly worn out rears does not cause a problem in the real world. as long as they are the same make and tread wear on the same axle.
