Tyres

[Kiwivan]

Depends on what driving you are doing. 50 series are low profile designed for less sidewall flex for higher stability cornering at speed. 60 is heaps low enough profile for a old Holden driven normally on the highway.
Tyre size works like this....... 225 = width of tyre across the tread.
60 = 60% of the width of the tread is how high the sidewall is. So a 225 60 will stand higher than a 205 60 because 60% of 205 is less than 60% of 225.
50 = 50% of the tread width so therefore it is less height in the sidewall. Less height in the sidewall = less sidewall flex and therefore less tyre roll when cornering.

Just remember that low profile also equals much more chance of a pinch flat or sidewall ripping out if you ever drive on gravel roads. That is why I cant use a 50 profile tyre.

There are also speed ratings on tyres but unless you are doing track days these are of less importance.

Also tyres are the only thing that connects your car to the road so spend as much money as you can afford. Cheap tyres are just that.

I do not buy second hand or cheap tyres,Infact I just paid 400 a tyre for one of the other cars we have.But I gather that a 60's profile would be a better tyre for the old girl.All so is going to be is a weekend cruzer!.

the last time i paid near 400 a tyre was for some 315/35/17s for my vq statesman 1 tonner...i use second hand tyres off the wrecks in my yard for my 14 and 15 inch cars..

Now just to sum things up if I put 235x60x14 on the 6 inch rims with 25mm below standed springs will I have any issues,She is power steer with a complete rebuilt front end(tie rods, ball joints, etc)There will be new springs and shocks,I am looking at putting Konis on her with cobra springs.

ps or has anyone else got a suggestion as I want to make it ride quite well(for a 70's van)

i would buy 215 / 65 /14 for 14 x 6 GTS rims. run them all round....
my second choice would be 205/ 65 /14

don't go any wider than 225 on a 6 inch as the tyres baloon out too much, and i have found 50 and to a lesser extend 60 series tyres on old holdens up front make them dart all over the road a bit - but yeah, particularly with 50 series...

50 series tyres wear unevenly too i have found, i often find them with 80 percent tread with the shoulder down to the canvas.
this is to do with set up i know, but finding that set up is difficult.

225 / 235 is more for a 7' rim

if you go wide up front, it highlights how good or bad your top steering control arm rubbers are...
