    The new size is perfect and will have a negligible effect on the speedo. However the extra width of the tyre will probably lead to a very slight increase in fuel consumption. But on the plus side it will give you better road grip and better cornering due to the the smaller sidewall.

    On second thought effect on steering will also be negligible since your new tyre's sidewall would measure 120.25mm as compared to the old tyre which would be 122.5. So its just better road grip and that's it.

    Well according my experience, you should not feel no difference at all, and yes you can change tyres from 175/70/R14 to 185/65/R14. The only change would be that your ride height would be reduced roughly by 1mm. Yes 1mm!!! I know there will be a lot of question and I am ready

    Ride height would lower by 2.25mm, not 1 mm.

    Salam All,
    Thanks "whiteangel", "Racerf1", "levin" for your information and expert advice, man its a big help.
    Let me just go on more details regarding my question., I just notice that Corolla XLi and GLi comes with 175/70/R14 and SE 185/65/R15 (engine different) and Corolla 2.0D (175/70/R14) and 2.0D Salon (185/65/R14) have the same engine.
    1, Does it means that (175/70/R14) is for Economy and (185/65/R14) is for Luxeary and all have diffeerent speodo meter setting and fule consumption?
    2, I notice here (this website) guys hate (175/70/R14) size tyre and every one wants to change them, why?
    3, Can I get the Alloy Wheel for (175/7/R14)?
    4, Same alloy can be use for both tyres?

    ok, this is what i have observed:

    Case#1
    car: Corolla xli 04
    have done 16K Km's on stock rims and Stock tyres (General). the driver has no complaints with the tyres so far and is veryyyyyy happy with them. hes an old **** and has a lot of experience with cars. no damage to suspension, excellent consumption and no handling issues. i have been with him and the ride is fine...not many ppl would agree but the guy is pretty satisfied!!

    Case#2
    Car: Corolla Altis
    the guy actually wanted a civic but ended up in buying Altis. so this changes the whole scenario...anyways, this is what he did with his car. got the Rims n tyres replaced with Rim size 15" and tyre Size 185/65 Yoko. the car has very poor handling. it scared the **** outta me while just turning the car at 90Km/Hr at the constitution avenue (In front of National assembly round about, goin towards Radio Pak). the owner feels the same...when you turn...it feels you have turned the wheel too much...you pull the wheel back and you feel its gonna go the other way...funny isnt it?? you get the feeling that the car wants to go straight...n ya i wasnt accelerating at that time. Ride is bumpy, u feel the hardness of the tyres. In so many other words...i would say "Wrong Move".

    Case#3
    Car: Corolla Gli 05
    The car has done 4K. the owner changed the tyres n rims to Rim size 15” and 185/70 profile. No complaints so far except for consumption. It has increased. I haven’t driven it so don’t know much about handling and road grip issues.

    Case#4
    Car: Corolla Gli 06
    this would be my experience. the car has done 350Km's. im running it on stock tyres n Rims. so far so good i would say. ride is smooth, handling is fine...road grip...i havent tried locking the wheels yet. but i would change the tyres to Yoko 175/70. other's experiences might be different but i would not change the original specs. n ya, excellent consumption maybe cuz im not pushing it much at the moment. i intend to keep it this way!

    You just made an engineers mistake, tell me how would you reduce tyres size by 2.25mm and the answer lies in this question and your mistakes
