View Full Version : Best tyre combination?

Whats the best tyre combo for a lowered front end and stock rear?

I've been told Smart car tyres (145 60 15) are the best for the front, but what about the back?

Depends whats going on at the rear, if its stock and you want the nose down arse up stance then slap some 205/70/15's on or 195/70/15's.

If its low at the rear aswell, then try 185/65/15.

it's stock at the minute, 165s on it. Suppose I could go in between and go for 195s.

there is a tyre size calculator on www.partsemporium.co.uk which will show you the difference in the overall height of different combinations to show you how it'll affect you stance.

cheers dude...

according to that, 145 65 15s on the front with 195 70 15s on the back will create a difference of 85mm. With 205s on the back it 99mm!!! :shock:

145/65/15 on the front with the adjusters wound down, short shocks and long travel ball joints, then 205/70/15's give you a stance like this:



you know it makes sense :D

is it on bricks at the front cos it looks like your front wheels have been nicked :D

big tyres on the back will fill the arches a bit and get you pointed down a bit more 8)

I presume you fitted castor shims at the front, cos you'll need em with that stance.

Looking good tho!

no castor shims... didn't know whether or not i'd need them. Don't even know what they do to be honest.

Seems to drive ok, bumpy but sticks to the road well!

The beams only been lowered slightly, probably got another 2-3inches in it (I think??!!) :shock: Still need to lift it up to get a trolley jack under it tho :roll:

So tell me, what do castor shims do... everyone knows of them but no-one seems to know what they do or why you need to fit them!! :oops:

What ya reckon to how its look tho?? Not enough rake?

looking good to me but i'm a fan of real big rake :D

If you put the nose down and keep the arse up your steering will go very light and funny. Castor shims cure that easily by correcting the angle of the beam.

Easy to fit, slacken off the beam bolts, slip em in and tighten up!

You may find things easier if you get long bottom bolts at the same time.

cost is around a tenner.

nice one rapid... all makes sense now :D

I'll see how it goes.... it's gonna stay as it is for the time being until I can afford tyres for the back. Gotta get the tyres sorted for the front fairly soon tho... the ones on it now are on loan..
