Different brand tyres front and back

Post by celica » Wed Jun 24, 2015 10:39 am

How important is it to have same brand front and back

I know not to mix it on the same axle, but how about front and back

Thanks

Gone for non runflat Falkens rear and about to replace the badly worn rft fronts

So currently no issues; but do I decide to match with Falkens 453 or uniroyal rainsport 3

Back to the theme Celica posted. On my 3.0d the rears wear more quickly than the fronts.  I have run-flat Contis all round - 250 x 50 x 19 x 107on the front and 285 x 45 x 19 x 111 on the rears. The rears run off at both the centre and inside edge leaving me with fronts that have much more life left.  I've got 2 sets of part-worn front Contis (one pair on at the moment and one from the last time I renewed all 4 at once) and soon will have to change the rears again.  Now for the key question - do I get another pair of summer run-flat Contis for the rear to match the fronts or begin the process of changing brand? This is the same question Celica is asking. other possibilities are run-flat Goodyears that are now fitted on the newish X5s, or run-flat Bridgestones.  I can't recall any difference between Bridgestones that I had in the past and the ride on Contis, but can anyone comment on the newer Goodyear run flats?  Please no comments about non-run flats as we've had lots of posts about them and I want to only change the rears whilst having run-flats on the front for a while yet.

Best wishes,

Graeme

The more I think about it
In an ideal world same brand and age on all four corners

But I've been running falken nrft rear and rft bridgestone I think up front with no real issue

So I'm thinking of going uniroyal upfront as they are the better tyre apparently
Also £20 cheaper in total to put towards a wheel alignment

One option is get a set of winter wheels as they are all 255/50/19  ! They are also et48 on the X5 but are still staggered on the X6 front are et48 rears et18 . Unfortunately they don't fit the E70 without having the rears bored out to 74.1 so don't be caught out by a cheap set of X6 wheels that say they fit the X5 as they mean the E53 which have smaller centre hubs all round !
Pm me if you need any more help ?
Regarding the Goodyear tyres they have been having good revues .

I've got the X6 wheels, had them bored for £10/wheel. Now have a nice staggered winter setup.
