I just had a wheel alignment done, and asked for them to rotate the tyres while they were at it.

My car is a rear wheel drive sedan with non-directional tires.

The tyre place did a straight front to back rotation, but everything I have read said for non-directional tires that when moving the front to rear you should cross them over as well (i.e. left to right).

I phone and queried them to confirm what they had done, and they said that on cars crossing them over isn't necessary.

This is a major tyre outlet, so I'm sure they know their stuff, but I am confused as to why everything I read says to cross the tyres over?

Generally a front to back swap is ideal. Just make sure that your RWD car does not have staggered fitment wheels as do lots of german cars.

You dont need to cross them over but if you wanted you could i suppose.
Since a wheel alignment is done the wheels should be swapped and balanced. My BMW's rears wear out 3X as fast as the fronts.. Mainly motorway driving and stop start around town.

In the old days of Cross-Ply tyres you did the rotational and diagonal cross with the 4 or if lucky enough to have a spare with 5 tyres

However with Radial tyres that is not the case and front to back is advised,

With 10 years in the tire industry you get to see alot.

I see reps being sold as genuine wheels, wrong tire sizes fitted to cars at dealerships, people selling goodride tires as a re branded goodyear lol...
Its a shocking industry with no consumer education and people can waltz on in and rip people blind.

Thanks for they replies guy.

Out of curiosity why is crossing them over not recommended in most instances anymore?

They are asymmetric, but are non-directional. So all four tyres are the same, there is no designated left and right tyre (just a "this side out" label).

most asymmetrical tyres only fit in one direction

hense why they may have just done a fwd to back rotation

Bridgestone Turanza Serenity Plus.

I'm sure the guys know what they are talking about, and the previous posts in this thread have also said that crossing them over isn't necessary - but I just don't understand why you wouldn't, as crossing them over using the traditional rotation pattern will give each tyre a "turn" in all four positions.

As above, they are asymmetrical but are non-directional.

they may not need a "turn" in all 4 positions though if the car is properly aligned they should wear evenly on each axle and the front to back just ensures each tyre wears at the same rate.

In a perfect world they may not, but doesn't crossing them over "covers more bases". What I mean is that it may not strictly be needed (assuming everything is properly aligned), but I can't see a downside to rotating the tyres through all 4 positions.

I'd like to understand the rationale of not crossing them over. Presumably, as long as the tyres are non-directional, there is no harm; and you have all the wheels off anyway - so why wouldn't you?

not really when the outside is still the outside, if you have camber on one side you will likely have it on the other (the car is aligned). so its really pointless.

if you flipped the tyres on the rim (which you cant with asymmetrical) then yes it would help with any uneven wear.

was there any uneven wear on them? no, then dont worry about it, its fine
