Which New Tyres For Tata Manza ?

[Tornado]

@jp ,I just wanted to gather enough info before interreacting with
the dealer.Because dealers usually try to sell whatever is available in their shelves.

 

[Tornado]

The tire specifications as per owner mannual is as follows.




BS website has following suggestion and the size is different than what is mentioned in the owner mannual. Select Tyre for your Vehicle - Passenger Car Tyres | Automobile Tyres | Truck & Bus Tyres | Potenza Tires | Turanza Tires | Dueler Tires| Bias Tires| Radial Tyres| Tubeless tires - India
Does this means BS wants me to fit 16 inch tyres on 15 inch wheels?

No,contact the car dealer where you purchased the car from.Not the tire dealer.If the car dealer doesn't have the information,contact the company.
What the BS website indicates is that you can fit the tires.But you need to upgrade the rims as per the required rim width that is needed for the particular tire.
Check the recommended upsizes in the same 15inch diameter wheels.Also if the tire is too wide you may need to go for a wider rim.As per your Manual the rim width is 5.5 inches

 

[Tornado]

What company specification?The company will give you an upsize chart.Why don't you contact the company and take a look at the recommended upsizes.

Please do not expect other TAI members to do all the work for you.

Now, I realized why some part of the above post is typed in 'bold'

@ jp , due to the persistent encouragement from you and others finally In gathered the courage to call the TATA company.The man said , He is sorry as he doesn't have info on tyres of manza and asked to contact nearest TATA workshop or the dealer from whom I purchased the car. But he can give info on new clubclass and 2112 manza !

Now, I do not have enough courage to call the morons at the dealership.

I talked with TATA concorde workshop , the spare part manager asked me to stick to the specifications given on owner's manual.

Workshop people are really lazy.It is upto you if you want to stick with the oem size.

Before upgrading,ask the dealer if he will mount one tire on the front and one tire on the back in the 195/60 R15 size.Try to turn the steering lock to lock and check the clearance in the front,load the car(with workshops guys) and check the clearance in the rear.If all goes well upgrade to 195/60 R15 else go to the stock size of 185/60 R15.

This is the best solution that I can think of for your situation.

I am sure you can up size to 195/60 R15 tires without any issues. I have seen people who has up sized from 14in to 17in Without any issues.

Xm2 vs primacy LC

:

Overall diameter of stock tyre is 602 mm.while that of primacy LC(195/60R 15) is 615 mm and that of XM2 (185 /65 R 15) is 621 mm.
How much improvement is expected in GC ?

wheather this diameter is mentioned for inflated tyres or the unfitted showroom tyres?

As the said primacy LC are wider than Xm2 , which would be better for FE? .And which would be better for handling and braking ?

One of the Manza tyre specification is 82T, how imp
ortant it is for me ?

 

[VivekRj.Dieselhead]

All the perimeters will be having a certain error due to change in size but everything would be more or less same. In "82 H" "82"Is the perimeter of max load it can take and "H" is the max speed. Don't think this much otherwise you won't be able to do even simple tasks like this.

 

[jarpickle]

195mm is the section width, 60 means 60% of 195=117mm aspect ratio(sidewall height)

The 195/60 R15 is 10mm wider and 6 mm taller than the 185/60 R15 stock tire.

Refer to your owner manual regarding the tire upsizes that can be used.If its not mentioned there contact the dealer.

Primacy LC 195/60 R15 88V is rated to 560kg per wheel and for a max speed of 240kmph(It will do max speed for just for 10 seconds though)

XM2 185/65 R15 88H 560kg per wheel and for a max speed of 210kmph(It will do max speed for just for 10 seconds though)
185mm is the section width, 65 means 65% of 185=120.25mm aspect ratio(sidewall height)
The 185/65 R15 is only 9.25 mm taller than the 185/60 R15 stock tire.

The stock tires are rated for less weight and speed compared to the PLC but less weight and same speed as compared to the XM2

The XM2 is taller so might cause scraping on full load.

Why don't you try my suggestion and get one tire in 195/60 R15 fitted onto the car and check clearance on lock to lock and full load in the front and full load in the rear.This will help you decide better.

I did this when I got my new tires.I could gauge how the tires looked on my stock rims and also the clearance.Saved some cash this way,as I thought I would need alloys with the new tires.

Both these tires might cause a 2% speedo error.You can gauge this by using GPS.

All these values are when the tires is not mounted on the rim.All tires are valued unladen.

 

[Tornado]

When ladden , xm2 (9.25 mm) extra height would reduce , am I right .? Height won't be an issue for manza wheel archesIMO.

Tire upgrade chart is not available in the mannual.And I am sure dealer and tata morons won't have better knowledge than TAI.They will keep on telling me to stic to stock size.

BTW , I read on report from manza owner on net who is happy with PLC , run 40kkm on it.

 

[jarpickle]

No it wont reduce that much, it will flex.If you drive at high speeds and turn at high speeds avoid the 185/65 R15 tire.You will need wider alloy wheels to make sure this does not happen.I would say stick with the 195/60 R15 if it fits on your stock rims and doesn't cause any clearance issues.

 

[Tornado]

Rim size is 5.5 which is ideally suited for xm2 , though pLc can be fitted on it , plc is ideal for 6 size rim hence I was inclined to ward xm2. I would be happy with increased GC too. Most of the speed breakers here on my route are unmarked hence it is possible that they go unnoticed when I am in hurry and with full load with normal speed possibility of scapping is experienced by me unless I reduce the speed.which is not possible always.

My driving style is ' always in hurry type' due to nature of my work.But I rarely get an opportunity to cross 100km ph . Six km of my daily 65 km route is ghat section.I just hate to sacrifice the torque as it needs to down shift so as to reduce the torque generated speeds.When at good speeds I am reluctant to
reduce the speeds on taking turns.

@jp , your suggestion of trial fitting is possible to implement only at the time of purchase and not now.

 

[jarpickle]

Yes, obviously the test fitting would be at the time of purchase.If you feel the XM2 suits your needs get it test fitted first.

@Tornado, as requested by you I checked my Manza's manual and stock tyres. It is the same.. 185/60 R15. Stock tyres are from Bridgestone B250. Hope this helps. As far as upgradation advise goes my suggestion is to go to a tyre dealer and ask him to show different options. You can compare (size etc) and take a call.. I had upgraded my Indica with Michelin tyres from 165 to 175 with no impact. Infact the road noise had reduced quite a bit...

 

[Tornado]

@sdbgl , what was the effect of increased width of the tyres on FE of your Indica ?


BTW , bridgestone no more produces the stock manza tyres .
