    Wheel Offsets

    Hi All. New here and new to owning a P38. I tried searching the forum but nothing obvious came up but apologise if my first Thread is a repeat.

    I'm in the process of slowly upgrading my range rover for off road use but still try and keep its onroad capabilities as good as possible.

    Have done the emergency EAS kit, upgraded the stereo, have installed Gen 3 bags and next is the wheels/tyres which will then be followed by a lift kit to suit the extended travel of the gen 3's.

    But for the current time I'm looking at rims for my off road set of tyres.

    Have decided to buy Kuhmo KL71 Mud Terrains as I will normally drive with the almost new Cooper Highway terrains already on it.

    So I need rims to suit 245/75/16 which I believe can be 16x7 or 16x8. These should be the maximum advised, almost 31 inch, before scraping may start to happen without a lift/spacers from my understanding.

    With the standard offset meant to be +57mm, if I get a less offset of say +30mm will the tyres stick out too far and end up scrubbing the outer part of the guards?

    Reason I ask is I'm trying to decide whether to buy a set of proper range rover alloys or some steelies that don't seem to come in anything as big an offset as 57mm in P38 stud pattern.

    I'm looking for bargain rims here as they won't be dress rims.

    Any suggestions? I would probably prefer steelies for off road use I think but not sure.

    I live in Sydney and planning on going out to Land Vehicle Spares at Silverdale to see what they have out there.

    Welcome to the forum,
    I cant help you on the offset question but keep your eye out for wheels on ebay as plent of people change from standard rims to "bling "type rims. (NOt my choice) and I picked up 5 rims with good tyres for $50 each. The wreckers will probably charge you more

    Stock standard HSE has 255/65/16 = 737.87 mm diameter
    245/75/16 = 773.68 mm " "

    You should be able to manage that on stock rims.
    I do recal a post about this tire size i think it was the max that you could go without scrubbing.

    You will rub! I have 255-70-16 muddies on mine and I've had to remove the front mudflaps, every now and then on full articulation the rears rub the inner guard, not heaps but enough to see the scuffs afterwards! Your 245-75's are slightly taller than mine, I reckon u could get away with it but you will definitely rub!

    For the rims, I would try to stick to LR alloys. They are an excellent and strong rim, but importantly they have really good bead retaining ring on the inside of them that stops the tyre from coming off the rim - makes like a bit more difficult for the tyre changers too, but they are some of the best at retaining tyres. Your options for these are 16x7, 16x8 and 18x8 in alloy and a handful of Disco2's came with steel 16x7's also. These are all the same +57 offset. The Disco2 and P38 rims are interchangable.

    wheels

    I am running 265/75/16 bighorns and have removed the front mudflaps and have no trouble with scraping, but on access height it will rub quite a bit.
    I just don't try to drive it on access, but in the bush, it flexes well with no problems. I am running Gen 3 as well and have tweaked the two higher settings for a little more clearance. The factory alloys are fine (mine are 8 inch) and if rims were offset further out then scraping would be a problem, particularly at the back of the front wheel arches. Longer bumpstops would also be good.

    OK. Thanks all for your guidance.

    Land Rover alloys it will be after hearing the strength and the comments about the bead.

    Will definitely stick with the +57 offset otherwise it's bound to scrape by the sound of it... And the look of it.

    Hmm 255/70/16 scrape slightly but no big problem, but 265/75/16 don't. I read about previous comments conflicting from car to car so suspected this might be brought up. It's the reason I chose 245/75/16 so I was more on the safe side. I'm not doubting either of you to be honest.

    Hey Parasnoop are you running bigger bump stops? I don't want to myself as it'll reduce articulation. Would only use them if I get the 2 inch spacer lift and longer shocks. I'm experimenting with the high setting up an inch with the gen 3 to see whether the extra inch height gained is better than reduced downwards stroke. First thoughts are it doesn't seem to pick wheels off the ground easier so sorta happy.

    To be honest I'd prefer 32's in the case I lift the car with the spacer kit supplied from hardrange but as I'm undecided its a difficult one.

    I wonder if the tyre shop will let me experiment at a cost of fitting a tyre. Any advice on how to get the car in its worst case to scrub in a tyre dealer? I'm guessing that sitting on the bump stops is not the lowest seeing as the axle is straight. Hmm maybe turn the eas off and let the air out of one side when on the high setting?? Or climb up a customer's car like monster truck style :-)

    You could put one front wheel on a hoist pad and raise the hoist! Saves putting k's on a new tyre!

    Mine only rubs under full articulation and it's not noticeable in car, only afterwards when I inspect the arches, however I can drive and turn lock to lock no worries in access height.

    I have had 265 70 16 ATs with never a hint of rubbing. I now have 265 75 16`s which are about 70% tread left. I have had very light scrubbing a couple of times on full lock from the front on uneven ground. I still have mudflaps so I suspect they are the contact spot but as yet I cannot see any marks. I would like to keep the flaps and maybe trim a bit off the lower edge if thats where they are rubbing.

    So did you ever have the tyres on when they were 100% and do any rock climbing or something that made your suspension go right up in the guards? What tyres? Are they AT or MT?

    I'm looking at MT so suspect the side lugs may encourage scrubbing and 265/75/16 would be risky. But I'd like to go 265/75/16 in the MT if I can.....
