Sorry, Tyre question!

Hi, I've been a covert member for a while but now have a question.

I need to replace the front tyres, I'd like to get all 4 replaced with Insa Turbo Rangers but budget and availability are a problem.

Would there be any issues If i put a new pair of rangers on the rear and leave my current (decent) wranglers (from the rear) on the front for a couple of months?

Would really appreciate the advice, Thanks!

Allway's put new tyre's on the back. somebody will be along soon with all the technicle issues regarding tyre diameter.

NOTE: the following is from experience only, not from technical knowledge, so it could be complete rubbish.

How much tread is left on the Wranglers?
I think if 5mm or more you should be ok for a few months, just bear in mind the wear will increase more on a worn tyre than on a new one so don't leave it too long.
If you start noticing a feathering pattern of wear on the rears, or your VCU is getting noticeably warm, you've left it too long!

To be safe you could remove the prop in the meantime, then it wouldn't matter how worn they are!

I can totally empathise with finances being a controlling restraint as everyone can't afford 4 new tyres at once.

However it would be a bad move if getting it wrong was to provoke later repair bills as a result.

So I would be checking the actual circumference of the Wranglers and the new Rangers.

Personally I would be happy only if the difference was 3 cms or less.

Hi, Thanks for prompt replies!

It's the fronts that need replacing, the tracking has been out for a while and one in particular is exceptionally close to the limit!

Just wondered if there'd be any drivetrain issues with new rangers on the rear (think they come with 15mm tread when new) and around 5 or 6mm on the front tyres (these will be the wranglers off the rear).

Cheers

The tread depth is really irrelevant - that's why I said to measure the actual circumference.

As the Rangers are a much more off-road tyre with a chunky tread pattern they will have quite different handling characteristics.

I would advice getting the 2nd pair of Rangers as soon as you can afford them and in the meantime take it easy on the corners - especially in the wet as off-road tyres usually have less grip on ashphalt.

Be very carefull, i put 2 new tyres on the rear last month, they were much different in size to the front and it shagged the rear diff, thats what i know, what other damage has been caused who knows!

Well if ya all do a search Hippo did a thread about your very subject. If I remember correctly It was new tyres on the front old on the back. But like I said Hippo did a thread about so check to make sure As little as 3-4mm difference in the actual circumference can fook your drive system real good

Regardless of "newness" tyres with the greater diameter must go on the back as the gear ratio in the rear diff is lower than the front and having the same or slightly larger dia tyres on the back means that the slip rate in the VCU remains within acceptable limits.

Also, if you can stretch to tyres that are not re-moulds then I would advise you do that. Right now 4x4 tyres have a ridiculously good price on Pirelli STR's - one of the best Hippo tyres by far.

Said I wasn't sure and that Hippo did a very technical thread about tyres and the ird and cvj failures and there pit falls

Indeed you did, just thought I should clarify . Hippo's thread are very useful.

Be warned , mismatched tyres will kill a freelander ones drive train take note of the advise given

If you want to stick them on, do it, but remove the prop! It will stop the drive train wind up and give you the time to afford the new tyres.

Even to the extent of offering to swap em meself as I now what’s going to happen. I just can't see why a formal statement int been sent round all tyre fitters to update em wiff a formal guideline in Freelander 1 tyre fitting, or to ask on ere first. Same as getting a battery fer me v6. They all have books that tell you to fit one that’s much smaller than the Land Rover Freelander Driver Hand Book recommendation for the v6. Un un un they tells you the LRDHB is wrong. Last time I bought a battery I was served by a disco owner. After the above happened again, he said he’d sell me what I wanted. So I bought as per the LRDHB a proper sized battery.

Tis a tratter boy conspiracy to destroy all Freelanders. That’s what I ses.

30mm??

In terms of circumference, that's a tiny difference. Diameter or radius, that's a whole other matter!

Here's my real world calculations to clarify my statement that under 30mm would be OK in my opinion.

I measured my Summer tyres when I took them off back in November.

All of them are Continental and exactly the same model.

The nearly new rears had a circumference of 2192mm with a tread depth of 8mm.

The fronts with a tread depth of 3.5mm have a circumference of 2164mm

That's a difference of 28mm in circumference.

I intend running the fronts down to 2mm tread depth, at which point the rears will probably have worn down to around 6.5 / 7.0mm.

I firmly believe that if you have the same tyres all round then you need to keep the tread depth difference to 5mm or less.

I now swap my winter tyres round regulary at 5k to equalize them - but I was too late to start doing that with the summer tyres so they are now too big a mismatch to swap front to rear.

So - back to my original opinion that the bigger circumference go on the rear as long as the difference is 30mm or less.

Of course everyone must do as they think best.

Also make sure yer tyres are pumped up propper. All with the same pressure including the spare.

I measured my tyres last year when investigating problems. If yer get hold of a flexible sewing measuring tape then yer can easily measure the circumference of yer tyre. Jack up wheel to measure.
