Title: 235x85x16 Tyre pressures UPDATE!
Post by: 500bhp on December 11, 2005, 14:36:39: Hi........I am changing my tyres to 235x85x16 Maxima's http://www.algarpneus.pt/fedima/fedima.htm
Can anyone recommend the pressures to run them at for road use.

Post by: Xtremeteam on December 11, 2005, 14:44:42: they look like firestone SAT's,got them on my 90 :wink: i run them at 26 for daily driving & when playing go down to about 10psi

Post by: Bulli on December 11, 2005, 14:47:55: MIke sounds spot on . I normally dont go as low as 10 but depends on conditions.

Post by: 500bhp on December 11, 2005, 14:50:10: Is the 26 psi front and rear ?

Post by: Xtremeteam on December 11, 2005, 15:49:08: yep,26 all round

be warned though,they are ****** scary in the wet,they make there own mind up when they want to grip on wet tarmac

Post by: muddyweb on December 11, 2005, 16:44:34: Before you part with your money, make sure they carry the appropriate 'E' mark and speed rating for road use... you could find yourself without insurance if they don't :shock:

Post by: 500bhp on December 11, 2005, 23:09:50: They do have the correct approvel for road use....but I must admit 26 psi seems low for the weight of a Discovery....but if you guys are sure I will go with it.

Post by: Bulli on December 11, 2005, 23:19:16: I run mine generally around 26, occasionally up to 30 if im going on a very long run but they dont feel as sure footed somehow. Yeah Tims right check they are legal for your disco....uninsured isnt somewhere you want to go.

Post by: 500bhp on December 12, 2005, 17:22:49: In the end I got 7.50x16, should I still run them at 26psi for road use ?
Title: 235x85x16 Tyre pressures UPDATE!
Post by: thermidorthelobster on December 12, 2005, 17:40:55: Wow, I normally run at about 35psi at the front and 32psi at the back. I found I was getting a lot of wear at 25psi.

The 101 tyres are now at 45psi, which is probably overkill, but it's bloody heavy.

Post by: MuddyMachine on December 12, 2005, 17:56:17: I run my 238/85/16s at 30psi all round. That semms to work best for me.

Post by: 500bhp on December 12, 2005, 18:08:47: So should the pressures be the same for 7.50 x 16 as used with 235x85x16............Does anyone on here run on 7.50 x 16 Sat's
Title: 235x85x16 Tyre pressures UPDATE!
Post by: Xtremeteam on December 12, 2005, 18:32:21: yes,i run 750 sat's,got mine at 30 just now to try & its even worse in the wet,will prob put it back to 26 tommorow
Title: 235x85x16 Tyre pressures UPDATE!
Post by: Matt_H on December 12, 2005, 21:10:23: I run mine at what the manual said... 30 front, 40 rear.. or it may be 28 front 38 rear.

no problems gripping anything in any weather, on 235/85/16 grizzly claws :-)

Post by: MuddyMachine on December 18, 2005, 21:48:01: ive got 235/85/16s on mine with 1" spaces, I had to trim the rear arches and the front valence

Post by: Matt_H on December 18, 2005, 22:02:10: it all depends on what tyres - I used grizzly claws and they would catch on the plastic sill covers..

I therefore gor a set of sill bars made a bit shorter than the plastic ones (which are now for sale Ã‚Â£125!)

I also cut the wheel arches back by at least one inch all round, then used some knock on edging to make it MOT friendly.

I also added a set of exted bump stops from paddock spares. (mine maybe for sale)

Oh then there are extended brake lines you may want too (also maybe for sale)

HTH
