Wheels & offset


Recommended Posts

I'm looking to replace the tyres on my 90 and after searching all the threads have got it down to 235/85 or 265/75. I've also worked out that I'll need 6-7in or 7-8in rims to suit and may have to adjust the steering stops but now I've got confused. I notice talk of different offsets, spacers and whether the rim needs to be a tubeless or tubed. My plan was to look in the mags and see what offers there are but will I get the right spec? What are the different wheel types - steel,spoked,alloy, boost, wolf?

At present I have 16x6JK33 rims with 205 tyres and will probably use it more on tarmac than off road but want the ability to play.

Any help will stop my head spinning!

Are you wanting a complete new wheel and tyre package, or are you just wanting some new tyres?

If you want a package i'd look at some 265/75's on 7" wheels of your choice. You could even pick up some used alloys or disco steels and fit the tyres to them.

I think the 235/85's will just about squeeze on to your existing 6" wheels, so if you want to retain your existing steels, then the 235/85 is your only real option.

Forget tubed tyres, total faff and only required for some very old rims (or some wolf rims) that dont have the beads to lock a tubeless tyre in place. All alloys and most steels you'll find will take normal tubeless tyres.

The steering stops is something that will depend on exactly which combo you get. Its simply a case of finding out if they catch, and if they do, adjusting the stops until they dont.

There are only two types of wheel. Steel and Alloy. The other things your seeing (8 spoke, modular, wolf etc) are specific styles of rim. Some of those styles are alloy (like boost, deep dish, freestyle etc) and some are aftermarket steels (8 spoke and modular) Wolf rims are Landrover OEM for military vehicles and are extremely heavy duty.

You need to decide what you actually want to achieve, then go from there.

/\/\/\ wot he said,

dont normally advise this - but i suggest you buy any of the landrover glossy magazines and have a gander and see what takes your fancy in your price range,

virtually all aftermarket STEEL wheels - like modulars and 8 spokes - will have better backspacing (stick out more) and will fit both the tyre sizes you mention without the need to adjust lockstops (or only very slightly).

Most alloys wont have the backspacing of the aftermarket steelies. Plus they look rubbish if scratched up and they aint really the best idea of you plan on offroading to any real extent. And they usually cost more.

most cost effective if going for new tyres AND wheels is to buy a special offer package deal.

I use Silverline in Coventry.

They usually have a big 2-page advert in LRO and LRM and have a decent selection. Plus they're at most of the shows.

Speak to Chris on 01926 496668.

For what it's worth, my 110 has 16x8 alloy rims with Cooper STT 285/75/16 tyres. No suspension or steering mods needed.

The offset is good, so they sit very nicely.

Steel modulars are cheap and available everywhere. The offset is good and they will come in sizes to suit most tyres.

Depends what you want and how much ££ you have to spend.

This is a good package for the price and the tyres are good off road and quite on road.

http://cgi.ebay.co.uk/INSA-TURBO-SAHARA-4X4-MUD-TYRE-235-8516-W-T-package_W0QQitemZ280464357901QQcmdZViewItemQQptZUK_Cars_Tyres_RL?hash=item414cfa7a0d

Note these are remoulds but INSA have good a good reputation. Kuhmo offer reasonable priced 'new' tyres as do BF Goodrich, which are more expensive

If you want more road biased look for an AT (All Terrian) tread patern.

235/85 X 16 or the slightly wider 265/75 x 16 are the size you need. As previous reply 235/85 for you existing rims are probably preferable.

IMHO avoid 152 tyre and wheel deals and stick with 16" wheels.

Ther are many wheel styles and tyre choices. A trip to yopur local idependant LR specialist is probably a good idea if your not sure.

Just thought I'd mention that your speedo will under read if it's one for SWB tyres (like 205/80) rather than LWB (like 235/85). So that'll need changing or you need to put on the new speed markers.

In my experince the slight increase in tyre size usually correct the speedo reading as most leave the factory reading under the actual speed wheen checked with a GPS. Fitting 235/85 to my classic range rover that had 205/80 as satandard fittment made the speedo reading spot on :)

A set of unfasionable OE alloys (7" wide x 16" diameter) off fleabay will probably be cheaper than a set of new wheels if you are looking to keep the costs down, but make sure you get the wheelnuts. There are some good deals on wheels and tyres about though.....

If I remember correctly, the usual size for modulars is 7" wide and upwards.

Silverline, nr Warwick, and others sell modular lookalikes - they aren't modular but do have round holes, but not the screws.

235/85R16 tyres are a standard LR size for a 7x16 rim, usually when alloys are specified from new for a 90.....

Hope this helps!

Thanks for all the info, following which I'm almost set on 235/85R16 on 6.5" steel (modular) rims.

Just the actual tyre to choose now but there's loads of advice on that on previous topics.

:D

I suppose your present rims are the rostyles seen on your avatar picture, since they have the dimensions you mention?

I've run 235/85R16 on rostyles. The 6" rim width seemed to fit the tyre well.

Rostyle rims for the Land Rover have been made both as tubed and tubeless. Look for the word "TUBELESS" or "TUBED" stamped into the metal around the center hole.

If you have the tubeless type, I suggest you keep the rims and fit new 235/85R16 tyres.

If you have the tubed type, scrap them and fit something else unless you absolutely want tubes for some reason. Good suggestions for replacements have been provided by others in this thread.

I run 235 85's, on a 7 inch modular with zero offset, my front caliper hits the hub before the tyres rub the radius arms, and,the tyres don't stick out past the arches, ya can't get better than that, well, for me anyway. . . Steering lock is critical in rtvs!!

Good choice. Oversize tyres reduce performance on dry roads and reduce grip off road or on wet tarmac and make steering heavier and less precise. They are only of benefit on deep snow or sand.

If by playing you mean laning, then BFG ATs would be ideal. If you mean pay and play sites in old quarries, MTs would be better off road, but your on-road driving will be compromised more than with ATs.

Check with the vendors what offset any modulars or 8-spokes have - I had 6 8spokes, and two of them transpired to have 15mm different offset to the others, though they were otherwise identical. The more widely spaced versions would stick out beyond the wheel arches, but the narrower spaced versions fill the arches very neatly with only a little of the sidewall protruding.

Also look here for wheel/rim/tyre info: http://www.carbibles.com/tyre_bible_pg4.html

On my 110 I have 265/75R16 and fitted wheel spacers to improve the abysmal turning circle. Admittedly, they did protrude a little beyond the original wheel arch eyebrows, but I've recently fitted a set of wider eyebrows, and I'm very pleased with the overall performance and looks.
