Tyre upgrade for Def 110

[Prith]

Guys, I have a choice of the following:

1. 285/75/16

2. 315/70/16

Can I use the 315 on my Defender 110. It has a 2" Suspension lift.

315s are massive, and very likely need extended arches to cover.

I think it depends a lot on the dish depth of your rim, with a deeper dish you push the wheel further out, making the wider tyre not rub on the inside, 

but as Bowie says you will just be throwing MORE mud past your arches.

I do know that 900/16 tyres (255/100r16) are about 36" and they rub on the radius arm.

the 315's are about 33,4"

the standard 235's are about 31,7"

315 would be a hell of a strain on the steering components.

315 will throw sh*te all up the sides of the truck and you won't be able to see anything through the side window / wing mirror. Extended arches may not cover it.

I think this truck has 315's and the +2" arches:

I have big arches so no issues of the mud throwing up. My Wheels are 16"  x 8" with Zero offset. Totally confused to go either 285/s or 315s?

If you like filled arches 285. If you like over stuffed arches 315. I think you need 10" rims for 315 so your choice may be made for you. I run 285 75x16 on 45 and 255 85x16 on the 110.

I'd go with the 285s personally, you will soon get fed up of clearing mud from your windows, mirrors and door locks with the 315s. It's also cheaper in that you don't require extended arches and possibly new wheels.

I know lots of you are saying 315 is massive. But it's no bigger than a 12.50 tyre, which is a pretty common size in some parts of the world.

i.e. a 35.12.50R15

315mm = 12.4"

I suspect you need a 10 inch wide rim for such a tyre however to be 'legal'.

 

With the two sizes listed by the op, the 315 will be about 1/2" taller and slightly wider. Will probably look quite a bit more chunky.

[FridgeFreezer]

12.50 is quite wide for a Land Rover though.

And I can confirm that throwing mud and sh*te up the sides of the vehicle, filling locks, window runners and door handles with grit does get old after a while.

[Chicken Drumstick]

I agree it is quite wide, but not ultra rare IMO. Lots of the blinged up Defenders round here run tyres of that sort of width it seems.

As for throwing mud up the sides, I agree. Although it's not always as clear cut as you might think. Got some 235/85's that throw way more mud up the side of the vehicle than some 33.11.50's do.

I'm running 35/12.5 x 15 BF Goodrich on zero offset rims. They are actually very good, I have the wider arches and its quite reasonable.

[Bowie69]

A lot of people do run 315s... they are however totally rubbish

[Ex Member]

Has anyone here paid attention to the fact that he said he already has oversized arches?  Either size should be fine.  You will most likely need extended bump stops in the rear with the 315s.  Really, even with the 285s.  A lift does not really change clearance.  To properly check clearance, remove a spring and check full compression.

[Bowie69]

Yes I have, but even with these you will still gallons of liquid mud up the doors and through the windows.

[dangerous doug]

33 12.50 r15 bfgs on my 110. They came on the truck at standard height and fit fine. You will want wheel spacers or a -32 offset rim to retain steering lock

 

they do throw a bit of mud about. There is usually a nice lump inside the cab where it gets thrown up during footy down time while steering. I like them though. Well behaved on the road and really good Offroad when you air them down a little

[Prith]

Thank you all for the post and so much information. Frankly I hardly do serious off roading. Mostly greenlaning here in Bangalore. So the question of throwing mud does not arise. I already have wide wheel arches and also a 30mm wheel spacers. 

I plan to use either 285/75/16 or 315/70/16 on my Zero Offset 16" x 8" Steel Modular wheels. A friend of mine has 285's and they look small on his 90. I cannot keep buying tyres hence I requested all you experience people if 315/75/16 is ok?

90% of the time I will be using the landy on road. 10% is on sundays when I do some green laning. I would prefer the bigger size which is 315 than the 285's but still confused. Does anyone have a picture of their landy with 315/70/16s on it versus 285/75/16s?
