Dilemma! which mud terrain & what size?

[Reggieroo]

I'm ready for a new set of mt tyres but can't decide which type or size to go for. I'd like to raise my diffs up off thre floor a little more.

I currently have Greenway Machos in 235/85/16 on  my RRC but now one has a puncture & I think its past its reparable life.

I'm fitting a 2" body lift as well as the 2" suspension lift I already have so I've been thinking of going slightly bigger but there doesn't seem to be much out there within a reasonable budget. It seems unless you spent a fortune you are limited to the same size.

If I have to go for a 32" like I've already got, I've been considering the Insa Turbo special tracks but not to sure as I have to use the motorways a few times a week covering a couple of  hundred miles. I'm not too fussed about the noise as these old RRCs aren't exactly quite & aerodynamic on the motorways.

Is there any differance in the height between a 265/75/16 & a 235/85/16 & are these slightly bigger than my current tyres as the Insa's are remolds?

Idealy I'd like a 33" tyre

a 265/75 is slightly lower than a 235/85 of the same make/type.

I would consider insa turbos at 265/75 as they reportedly are approx 33"

Wouldn't the 235/85/16 be a little higher then than the 265/75/16? That would give me a little more diff clearance wouldn't it?

i have just taken off 235/85's durango MT's from my rangie and fitted 35's. only a couple inches difference in overall diameter i think. but with the 235's i didnt need to cut anything. i only have a 3" suspension lift aswell.

they were more than capable on and off road.

I was just wondering why you said you would consider the 265/75/16  :?

[davidlandy]

oh right

well on the insa turbo its said to be 33" tall plus being a 265 it would be 30mm wider. So overall it would look like a more meaty tyre and look better.

Well I'm almost sold on those at the moment, what I really need to do is to go & measure up the two different sizes & see what I think.

I've always leaned more towards the 235 skinnier tread as I thought it would cut through the mud better on the heavy Range Rover, but how much difference it makes I really don't know. Also like you said the 265 will look better & we do try & make our vehicles look better if poss don't we?

There is a 4x4 shop by me so I think I'll pop down with tape measure & have a look in the flesh.

[davidlandy]

i have run both 235s and 265s in the past and the digging through the mud thing I couldnt find any evidence of. Maybe with more extreme width differentials this theory would become more apparent.

anyway get yourself down to the shops and bring back some tyres!!

There's something wrong with yours then mate.

So you don't get any wind noise from the brick like shape at 70mph?

[Reggieroo]

Just got back from the shop & after measuring the 265/75/16 special track it was 32" tall. They only had the Insa Turbo Sahara in 235/85/16 & that was also 32" tall. I put it up against my own 235/35/16 Macho & the special track was about an 1" taller so it seems that all the different makes differ in size.

The Insa special track looked like a really good tyre though, the chap also recommended the new Kumho KL71. Just waiting on a price for 285/75/16.

70mph :-'

Lets just say at crusing speed my LSE is very quiet, no worse than a Mondeo at least.

Blue is noisey because of the tyres and the diffs are screwed, plus the exhaust.

[jjsaul]

i've been running insa special track 265/75R16 for over a year now

they are around 33inch tall

amazing in the sticky stuff and for climbing up hills / rocky stuff etc etc

cheap as well

do it...!

I can imagine your LSE is quiet as its probably quite mint & standard. Mines probably more like blue then with noisy diffs, tyres etc.

Are they alright on the road, you know when its wet etc. I don't expect it to handle like a race car but I do use it on the road a lot.

[Reggieroo]

Well I finally decided what to go for.

I ordered some of the Kumho KL71s in 33.12.5x15 with some 10x15 black modulars.......

[Range Rover Ron]

I'm running with 235/85/16 BFG MT's at the moment, when I change I'm planning to go to 255/85/16's, giving a bit more lift to the diffs.
I have a 2" lift and have the arches cut away.

Cheers..........

Not too bad on tarmac unless you drive like a lunatic.

They do wear fast if you do a lot of road mileage though.

[Reggieroo]

The 33" Kumhos seem to be elusive, nobody knows when there is going to be any in the UK so I went berserk & bought some 37" Creepy Crawlers. There sitting in my garage & they look massive, now I've just got to get them to fit............ :oops:

[Range Rover Blues]

Are you going to do anything about the gearing?

[Reggieroo]

Are you going to do anything about the gearing?

Well I won't be to begin with as I've ran out of cash but I'm sure it will be on the long list of mods, at the top I would say with the flexi arches.
They will probably be the first things I will need to do before I can use it much I guess.

At the moment it has a manual box with viscous coupling, but I have an auto box from a 93 Rangie V8 waiting to go in anytime soon, so I'm not 100% sure what transfer box I will need to use etc now that I'll have the bigger tyres fitted.

a 265/75 is slightly lower than a 235/85 of the same make/type.

Why's that?  If you do the maths they should be the same to within 0.1" diameter.

[crazymac]

Would a Defender transer box bring the gearing down to a useable level

The maths ................

265/75 x 16 = 31.65" diameter

(265 x 75%) x 2 = 397.5mm or 15.65 inches; on 16 inch rims that makes 31.65" diameter

235/85 x 16 = 31.73" diameter

(235 x 85%) x 3 = 399.5mm or 15.73 inches, on 16 inch rims that makes 31.73" diameter
