Swapping Tyre Size

[big-83n]

Hi all

 

I've been on rollaclub for a while now but haven't posted a whole lot. I've got a 1983 ke70.

 

At the moment it has the stock 13" rims on it, I however have a set of 13x5.5" mesh rims that I'm going to put on

 

The stockies have 165/75/13 tyres while the mesh rims have 185/65/13 tyres on them which are bald as buggery.

 

My question to you is, would it be possible to swap these tyres over and would they fit? Ie put the 165/75/13 tyres on the mesh rims

 

Thanks for your help

Yeah mate should be able to, alothough would put ur speedo out ill say

I'd dare say so, the speedo more than likely showing a speed slower than what you are actually doing. This is assuming your car currently has the correct tyre size fitted.

Thanks xr8racer

Try this

http://www.exploroz.com/Vehicle/Tyres/SizeCalc.aspx

Put in current tyre size and other one and see how far out they are.

Thats quite a good site, I did the comparison and my speedo will be 1.21km out at 100km/ph, so when I'm doing 100 on the speedo I'll actually be going 101.21

just to confirm here, you're taking the tyres off the stock rims that are on the car, putting them on your mesh wheels then back on the car?

 

this would mean that you have the exact same tyres on at the start and the end thus making no difference? :blinks:

[big-83n]

Yes that is correct

 

The difference is the width of the rim, the stock rims are only 4" wide while the mesh rims are 5.5" wide so the smaller tyre will be stretched a bit to fit

Oops...:blush: I'm glad someone read this thread correctly :lolcry: Hopefully the tyres you have on the car are the correct size for the car, therefore your speedo wont be out!

Ok thanks

 

Maybe I should have posed my question better

 

Will the stock tyres fit on the wider rims?

[Oh-KE]

They will fit fine. Then when you need new tyres you can fit wider ones..

 

Here is a good tyre size calculator if you need.

[KEhendo]

i use that miata.net calculator. quite good.

 

yes your stock tyres will fit on the new rims and no the speedo reading will not be effected.
