Tyre Types

[Temp]

Hi I'm new to the forum having just purchased a 99 2.8 4x4. It's great so far, however reading through the handbook I noticed it states that the tyres should all be of the same size, make, type & wear pattern. They're not, different makes front and rear same size though. So before I break the bad news to the missus (& the bank balance) and toddle off to the Tyre shop has anyone had the same situation and did it cause damage to the transmission?

You don't say which vehicle you have but it is obviously not a Galaxy. I have a 4x4 Ford Ranger which I use frequently both on and off the road so I can tell you that having a mismatch of tyre types should not harm the transmission. Legally I think you have to have the same type and make on each axle. That is to say dunlops on the front, Firestone on the rear. What you should'nt do is put dunlops on the left and firestone on the right. Other readers please correct me if I'm wrong :P

No it is a Galaxy. 2.8 Auto 4x4 GhiaX. (Guess it's all the bits Ford's had left from the Sirrea 4x4 line) I was assuming that having different tpyes of tyres front and rear could lead to a difference in rolling diameter, thus 'winding up' the transmission, but as it's only a guess I thought I ask the forum.

got told a long time ago its ok to have different tyre size on different axle

 

ie 15`s at the front and 16 at the rear

 

but i would not my self try to keep to one make

 

if u change them all u can fill safe knowing that the job has been done

 

james :P

4x4 Galaxy (as others) should have generally the same grip and rolling radius tyres all round.

 

There should be no problem mixing makes, provided they are done by axle.

 

It just makes the the 3 diffs life easier in a straight line, but in real life the front tyres would generally wear at a greater rate anyway....

 

Nay problem

Thanks for the info, but I thought b***er it and changed the tyres anyway. Cheers.
