If it has to be Bridgestone, then go in for 165/55 R14 72V Potenza GIII. Just make sure your new alloys are 5" wide.

and if i fit 13" alloys can i fit my current tyres with them(orignal tube type)

Why would you wanna do that? When you're going in for new alloys, might as well buy new tyres to go along with it. Moreover, tubeless tyres are far more superior, comfortable and safer.

14" on a zen the right sizes for good grip,perforamnce are:
1. 195/45/14r
2. 185/50/14r
on experience..the 165/55 will be a waste

[speedsatya]

but i dont think ,its possible to fit 195,185 with 14 inch rims on your stock suspensions.
also,what should be done to accomodate these wider tires,

Dude that's a stock carb Zen we're talking here. You plan on suggesting 195s on a 45 bhp car?

His acceleration and top speed will go down considerably. All grip and no acceleration ain't gonna make for an enjoyable driving experience.

no it wont..not to that extent and they will sit on 14" rims and they will not touch!!!!

thanks for quick replies guys but my zen aint stock have got free flow inc. manifold and expansion chamber and a k & n(stock replacement) & alwayz used shell helix ultra synthetic oil covered 97500km till date.... top speed reached till nw is 158 on western express highway @ 2 am and lookin foward for more speed....

[Shan2nu]

So, how much power do you think the car is producing now?

Anyway, we've given you the options. It's upto you now.

Hey 14 inchers or other just check if they fit and you can add them in ... I would personally suggest 185/50/14r with 5 1/2 j however please be aware of what the setup demands:

1) The steering is going to be harder
2) Ride will be a lil more bumpy than the stock tyres
3) Speed might get affected slightly due to rolling resistance (wont be too noticeable though)
4) You will feel a bit of a drop in the pickup and a speedo error

However

1) If the suspension is upto it you will have a great handling car as long as you dont raise it too high & No spacers between the discs and the rims
2) Awsome handling
3) Better braking

The choice is your's...

However what did you mean by "manifold and expansion chamber" on a car can you please elaborate more on expansion chamber???

hey Psycho wat the does the 5 1/2 j mean in this " 185/50/14r with 5 1/2 j " ??

[Shan2nu]

wat the does the 5 1/2 j mean in this " 185/50/14r with 5 1/2 j " ??

5 1/2 is the width of the wheel (measured in inches) and J refers to the construction and height of the rim edge.


Rim edges come in diff shapes which are denoted using alphabets like - J, JJ, K, JK, B, P and D.

It's very important that you buy tyres of the same alphabetical code, as that of the rim. Overlook this, and you risk the chance of the tyre comming off the rim while cornering.

J is the most common code on almost all Indian cars. The alloys that come on the Vtec are 5 1/2 JJ.

hi phycho...
Manifold ie heahers:this is the main component in the free-flow system. it is made up of pipes and calculated length so that the exhaust gases are evacuated from the engine cylinder quickly results in better performance and power of the engine.

Expansion chamber:this part of equipment fits in the system after the header. its main function is to boost torque to the engines power band. it can be fitted in the place of auxilary muffler.

[speedsatya]

anything wider than 165 will touch in the zen with stock suspensions.even 165/60r13 with 5j rims does touch on the RHS.

with 5.5 j rims ,anything will touch.even 155 wil touch..so you have to bend the body patra from the insides to protect the tire from getting cut.

so to be safe u have to stick to 4.5j or 5j rims.

anything wider than 165 will put unnecessary load on the suspension,

BTW why the f**** do you want to put 14 inch rims.stick to 13 inch rims.and go for 145,155 or 165 tires with 4.5 j or 5j rims.


anything wider u have to rais ethe suspension and th ehandling will be messed up.so no use of putting wider tires if you dont get better handling.



even with 165/60r13 ,u have to bend tha patra,and mabbe use slightly larger rubber pads in the rear to raise the height.

OK this typically works best for 2 strokes now can you please explain how you are using it with a 4 stroke and what are your primary lenghts for the headers and are they 4-1 or 4-2-1... and what are the measurements & angles of the Expansion Chamber... if you dont want to put it up on the forum you can PM me the details.

[sparco]

the free flow in my zen is 4:2:1 and regarding the expansion chamber you can visit www.automechexhausts.com and look for more details i really dont have much idea about it...
thx
