Widest tyre on sawtooth alloys

[ProjectDirector]

Am not sure if this was covered but I find it a pain to search.

Simple question, I want to put slightly wider tyres on my 2013 110, the current 235 wranglers are fantastic but a bit skinny. What is the optimal step up without the Tyres touching anywhere?
Current I have sawtooth alloys 7Jx16 factory wheels.

I have a mate running 265/75/16 on the sawtooths.

You could run terrafirma wheel spacers ( 25mm wider ) to get a wider footprint too. ( Note ; These are illegal according to ADR )

I wouldn't contemplate putting spacers and as you mentioned they are not legal, 265 sounds good but I would keep the profile the same at 85.

The other thing with the wranglers they don't stick out of the rim much and I tend to scratch the rims often when offroad, my friends cruiser has Micky Thompson and they are stick out of the rim (don't know the technical term) and he never scratches his rims.

Thank you

Do you mean the balloon hangs out past the rim OR do you mean they have rim protectors, i.e. a rib next to the bead that shields the rim from gutters etc

I think the second one

Hi mate,

I'm due to collect my new 110 in just over a week. I'm swapping my standard setup for some 265/75R16 Hankook Dynapro tyres and these will be on black steel King wheels with an offset of "0".

I've been assured these will not stick out beyond the arches and will not rub.

The 265's in this profile are almost the same OD as the OEM 235's. Only a very small difference.

Good luck with your choice. Hope you get something you're happy with.

Cheers

265/75-16 is near enough as makes no difference to the same rolling diameter as 235/85-16, the "75" profile is a percentage of the width of the tyre, which gives sidewall height (in this case being 75% of 265mm).

If you want to go up in size, not just wider, the biggest that will legally fit on stock alloys is 255/85-16 (33"), although they are still narrow.

285/75-16 is also a 33" tyre, however will not fit on +33mm offset wheels and legally requires an 8" rim (if i understand correctly sawtooths actually have less offset than the standard +33mm LR alloys, the offset should be written on your rim next to where it says 7Jx16, can you give this info so we can further advise?).

So really you have two, possibly 3 options, 265/75-16 (32"), 255/85-16 (33") which will both fit and 285/75-16 which is illegal and may not actually fit...

Hope that makes sense.

Cheers

Exciting times for you with new defender, what colour?

I will choose the Micky Thompson MTR 265/75/16

(if i understand correctly sawtooths actually have less offset than the standard +33mm LR alloys, ).

Sawtooth are +20mm offset.

A 255/85 on wolf rims (6.5" +20mm offset) rubs on the rear upper spring hanger. For some people it rubs a little, other a lot. A 265/75 on the a 7" rim with the same offset will likely encounter rubbing on the rear spring hanger. If you are the touring type it may not be a problem. If you like to get crossed up the extra width will come into play.

Not sure where on the rim the info is, would it be on the inside?

I guess there is nothing "simple" about the defender :)

I will choose the Micky Thompson MTR 265/75/16

Getting the Keswick green, with black wheel arches and white roof :)

I've no personal experience with them, but have heard many many good reviews of the Micky T's. Either way, get out there and have fun. I know I will. :D

Classic colour combo, well done and enjoy.
I doubt I will be changing tyres anytime soon, my 110 is only 8 months old so they still have lots of tread to go through.

[noyakfat]

Yep, good decision. I peaked a bit early in swapping them out. Hopefully I can sell the original boost alloys with continental conticross A/T's to recover some cost of the new shoes :)

Would 265/75-16 fit on sawtooth wheels with a 30mm spacer on a puma 90?

Yes, it will be the equivalent of a neg 10 offset. People are running 285/75's on zero offset with no rubbing. Your combo is 20mm narrower tyre with +10mm wider wheel track.

ps: welcome to the forum.

Thanks MLD. I haven't receide my D90 yet but have one on order. So would 285/75-16 fit on sawtooth with 30mm spacers or will they start rubbing the fenders? I will be driving in soft sand mainly so looking for widest tire I can fit.

[Doc130]

285/75 on neg 25 offset work well, you will need a set of flat dog flexi flares though to cover them

I would just stick with the 265/75/16 if you want to change. Land Rover Australia are not keen on any size outside the two "official" sizes for 90's and 110's. As stated before the 235/85/16 and 265/75/16 are mere millimeters apart in rolling diameter and therefore both approved.

Odd sizes other than those two have in the past given people difficulty in some cases on transmission and drive warranty claims.

And purely for information sake - wider tyres give you absolutely no benefit what so ever on sand... in fact they actually hinder your progress. A 235 General Grabber (as standard when your car is delivered) at 18Psi is by a country mile the best tyre on sand...

Best refer to the manufacturer's recommended rim width for a given tyre width. I think you will find most manufacturers will be recommending closer to 8" than 7" for a 285/75.

As for a 285/75 rubbing the fenders (which i take to be the wheel arches i.e. flares), not likely. A standard height defender usually will accommodate a 33" tyre without fouling the flares.

Interesting read that article referred to by Loubrey.

If you are after the tyre height of the 285/75 (33") and want to use the sawtooth rims you might be better with a 255/85 tyre. FYI a 235/85 (factory issue for most defenders) is the same (in fact marginally taller) than a 265/75 tyre. You might not like the thought of it, but the factory issue rubber might be the best solution to your problem. Spend the money you didn't spend on new rubber on another mod that will give you better return on investment.

Thanks for all the replies and very useful insight. The reason I was asking about the 285/75-16 size is because the tires I wanted to mount only come in that size and not in 265/75-16

[DiscoMick]

I understood on sand more width was a disadvantage because you have to push more sand in front of the tyre. Taller is better because it results in a longer tyre print without increasing the amount of sand to be pushed, or something like that.
