18 inch wheels help

<< < (3/4) > >>

Paul Holtom:
Also got disco 2 on 18's and have found exactly the same as you, with it pulling slightly to the left and the steering a bit vague. Have recently fitted the new General AT2 tyres to it and this has improved things a lot. Another tip I was given is to reduce the pressure in the rear tyres a bit, 30 psi if no weight, 36psi if towing, again this seems to help.

Spooky:

--- Quote from: "beast5680" ---where i used to work 2 guys had identical disco 2,s one with 18" wheels and 1 with 16" wheels having been in both the ride of the one with 16",s on was noticeably better than the 18" one the lower profile tyres on the 18" disco seemed to transmit more of the road thru to the cabin than the other one
--- End quote ---

This is because of the amount of 'give' available in the tyres; the lower the profile, the firmer the ride. Great for handling (sports cars), but lousy for everyday driving.

Incidentally, I recently had my 265/75-16 MT/Rs on the truck, and the ride was much better than with my normal A/Ts (245/70-16), which proves the above.  Shame about the extra noise though ... :roll:

Hi, since putting 18's on swmbo's disco2, it  tramline's, tends to wander a little & is a bit of a harder ride,

oh & yes you do get used to it, tyres need to be changed next week so any suggestions would be greatfull,

it never ever goes off road so looking for comfort & road grip more than anything else,

Thanks John.

wibble:
i concure with above if you need another vote. ick up my new td5 tomorrow, spoke to the dealer about fancy 18" alloys and he advised strongly against as they do tend to wander with tram linning, and i believe him as he did him self out of the £700 odd quid they would have come to, did it on an old style mini cooper s with fat tyres on too.  now that was a scary ride at speed :(scared):

would get the box etc checked tho just to be on the safe side, speshly as its still warranty covered :wink:

grizz:
Had an old E30 bmw with 215 35 18's on and lowered 100 mil, it only used to tramline if the road was really worn to the extent that you can see the hollows (since I live in norfolk it seemed to be most roads) sounds like the dealers pulling a fast one, see if he'll let you take another for a test drive for a comparison.
