tyre swap

right well i was bored today so after reading a thread somewhere saying you should always put new tyres onto the rear of ya gaylander i swapped mine over. so i put the nearly new khumos on the rear and the half worn pirrellis (which have a little bit of uneven wear)onto the front.
just got back after the school run and its like a different car,
as i reversed off my drive on full lock,took my foot off the loud pedal and where as before it used to come to a halt rather quickly it didn't. it appears that by just swapping the rubber has eliminated most of the wind up that occurs when reversing on full lock .
so anyway off i went and as i accelerated through 30 mph, big vibration through the whole car which disapears by the time you reach 40mph. does the same on deceleration now it did not do this before i swapped the tyres so i would come to the conclusion that the pirrellis are ****ed.
but why no vibration when they were on the rear? and could just a pair of worn tyres cause the (coming to an abrupt halt when reversing on full lock)senario that all gaylanders seem to suffer from to a lesser or greater degree.

i reckon its because yu dont have rear wheel steering!

Yup !
seems to cause all sorts of hastles .
Mine started to give a whine out the back diff, got worser over the next few days !

Put some air in the front tires , no more whine !

Yee- haa was i releived

Mine Were Set To 25 Psi As Reccomended In The Manual,loads Of Floppiness In The Front End,took Them Up To 35 All Round,like A New Hippo,what A Diff It Has Made,phewwww

Gary - thats how you should put new tyres on an Freelander - always to the rear.

It might be the case that your front wheels need balancing - this would be a cost effective place to start and may solve your issues.

I had a vibration through the steering wheel at 50MPH and a balance sorted mine out. Some of the weights had come adrift.

get em balanced, thats why they wobble at a certain speed

but heres the rub. . .the fronts wear a lot quicker, so if you start from new tires, it makes sense ta swap em when you start seeing wear ont front. . .or have i missed some earth skulduggery or summit

I just tend to wear the fronts out to the wear bars and then have a new pair fitted to the rear and old rears moved to the front. This wears out the oldest rubber first and keeps the rear axle moving slightly faster keeping the VCU happy.

Also keeps the best tyres at the rear which I read is best to avoid loosing the back end.

I'm just following instructions in my LR owners guide and what was mentioned in my haynes manual.

Ming - you dont have to worry bout tyres - your jet propulsion system seems to be working fine

the vibration is not through the steering wheel its through whole car like driveing on rumble strips on edge of motorway.anyway will get balance checked.
she has just gone out in it to get her hair done so i'll wait and see if she notices.might be a good excuse to get the AT's that i want.

I'd definately try balancing first - vibration can appear differently and exhibit different characteristics.

she noticed the vibration,told her the tyres are knackered so she is letting me get the set of AT's that i want. yippie!!!!!!!!!

This wears out the oldest rubber first and keeps the rear axle moving slightly faster keeping the VCU happy.</p>Dont wish to seem overly pedantic (or worse still a bit of a smartarse) but putting newer and hence bigger rolling diam tyres on the rear slows the rear prop shaft down which is a "good thing" as the rear prop already runs faster than the front on early FreelandersCheersIan HughesTassie

right well got a new set of 225/55/17 colway AT's on the gaylander now.
looks cool with the chunky tyres,get a bit more tyre noise but not noticable with the stereo on and at 47 quid a corner i'm not complaining.

If it makes you feal any better......

Put 2 new tyres on the front of mine 2 weeks ago.
Drove off the forecourt, got to 60 and couldn't begin to descride the vibration!!!
went back, had 2 new on the back (so 4 new all same) now drives like a new one.

Must be a VCU thing!

I had exactly the same all round pirrellis changed the front for 2 new kumho's loads of vibration. swapped em round part worn pirrellis onto front kumho's onto rear vibration all abouts gone except at around 65-70 none below or above, had em re-balanced no difference. suppose when I've saved up for another 2 new uns or her inddors makes one less visit to hairdressers then hopefully hippo should return to silent running.

it must be something to do with tyres from different manufacturers having slightly different diameters even though they say the same size on the side.sure i read a thread somewhere else about this.anyway before i had my new tyres fitted i took the pirrelli spare off and replaced it with one of the khumos i had(more tread).then when i went to fit the spare wheel cover on(i have one of those metal chrome ones)the catch would not meet to do it up so i had to adjust the catch by nearly an inch to get it to do upwhich made me think the khumos are quite a bit bigger than the pirellis

as you say Mr Rigden the Kumho's are bigger, I tried to put the spare wheel cover over mine(not posh enough to have the stainless steel type) which fits easily over the Pirrelli wouldn't fit over the Kumho. So still saving for another 2 but she's off t'hairdressers again this week coz we're goin art.
