Hi People,

wanted to know , if there is going to be any issue if you change your tyre from tube to tubless. (tubless for one wheel , remaining 3 wheels - tyre with tubes).

will it cause instability or should we go in for all tubless or all tyre with tubes.

thanks for ur help!

Sure Amit, the reason being all the remaing 4 tires(with tubes) are in gud condition & only the spare tire has  worn out badly. I find tubeless tires to be more durable when compared to the tire with tube, hence would like to change all tires to tubeless shortly.

I am no expert in tyres but as far as I know ... tubeless tyre improve the ride quality. So there must be sifnificant difference between tubed & tubeless tyre. Hence if only 1 of the operating tyre is tubeless then it may dis-balance the overall ride quality of your car. It can also be the case that the wear & tare on the single tubeless tyre or the other 3 would be more ... (Not sure) but disbalance can cause more ware on some tyres out of four.

Guys.... Plz correct if I am wrong

It is definitely not recommended to mix tubetype and tubeless tyres on the same axle. So if only one tyre is being changed, it should be of the same type and size (and preferably, with same tread pattern) as the tyre on the other side of the axle. E.g. if you are changing your back right tyre, put the same tyre as the one on your back left.

Although it is OK to mix tubetype and tubeelss on the front/back axles, it is not advisable. E.g. if you mount brand-new tubeless tyres on your front wheels and your rear wheels are old tubetype tyres, be prepared for some serious oversteer when you take corners at some speed. What will happen here is your front tyres will have great grip, which is not matched by your rear tyres, causing the rear to skid on sharp corners. Similarly, expect understeer for the reverse scenario (old tubetype on front, new tubeless on rear).

The best policy is to rotate tyres regularly (every 5000-7500 kms), along with regular wheel alignment/balancing, so that all tyres wear out evenly, and then replace all of them in one shot.

Don't put a new tyre with 3 older ones. Choose a used tyre of similar age (or just patch the earlier tyre for what its worth). You will always be an unhappy driver with mismatched tyres, for reasons explained above.

Rotate tyres regularly (each servicing is also not a bad idea) to avoid uneven wear. Do not run the spare for any longer duration than required, patch the puncture at the next available opportunity and replace the spare by the regular tyre. that way all 4 tyres wear evenly.

With even wear on all 4 tyres, you can replace all at once, and then continue with the replacement cycles in that manner.  I would replace the spare at every alternate regular tyre replacement. If you include spare in the tyre rotation, all 5 need replacement at the same time.

Yes you can do that. But I would like you to just pass time somehow till you are ready to replace all 4 tyres at once. That would give you a good chance to come back in the 4-tyres at once cycle.

Vibrations can also result from overinflation. Check if you are inflating your tyres to more than mfr recommendation. That may solve the immediate issue. If the hardening is due to ageing, and if there are cracks in tyres, better change all 4, without further delay. There are safety implications in persisting with old, cracking tyres.

Mixing tyres on the same axle, should be avoided, otherwise there is no problem in running two new and two old tyres on the same car.
