305/70/16 change to 18/20 inch without the stance


Recommended Posts

Hey Fellow LR owners, 

I'm currently running rims (16x10) on 305/70/16R Nitto Mud Grappler Tyres (33 inch)

They are off-road and i'm trying to get the closest alternative which is road legal as I drive in London and don't want to risk getting 3 points for each tyre. 

Current Alternative for same rims: ST PRO COOPER or the BFgoodrich KM3 only do these sizes but they are again, also offroad. They are less aggressive than the Nitto Mud Grapplers so I might raise less attention.

 

Changing Rim Sizes:  I think my only alternative and what makes sense ahead of a big brake build (6 pot Tarox) is to increase the rim size, and decrease the tyre profile, without losing the height of the defender 90. 

Would anyone be able to recommend what reduction in profile I could take with 18, and then 20 inch rims to keep the same look?

They're off-road biased, doesn't mean they're not allowed on the road. As long as they have the right markings for road use, all is ok. Or has London introduced some silly unenforceable regulation?

I will second this and am not aware of any new regulations for the UK or London

 

Awesome looking 90 though, can we have some more pictures please? What have you got under the bonnet? And which country is it from?

"Professional Off-Road" abbreviation: tyres for commercial traffic use. POR tyres are specially designed for bad rolling conditions or for deteriorated roads conditions. Information: POR tyres do not have EU labels as they do not meet the tyre EU labeling directives.

I seem to recall the "Professional Off-Road" classification was introduced to allow specialised tyres to still be sold, even if the manufacturers can't be bothered to do the testing necessary for the EU classification (the letters for noise, economy etc). Which could mean they are considered illegal for use on public roads.

As noted below, they have the POR marking, which I don't think is specifically road legal right? 

I'll get some more. There's a chevy V8 engine with NOS, something very special but isnt finished. Made in the UK but was in Europe for a bit, just brought it back into the uK.

This is what I was assuming.

You'd think they would tell you if not legal, on here, if they weren't:

I called them up and they said they were off-road use tyres.

So it looks like I might need to increase the rim size and decrease the tyre size in order to keep the height of the vehicle.

So if I understand this right you'd like to keep the 33" tyre diameter, but have something less aggressive that is definitely a road legal tread.

A number of brands make a 285/75R16 tyre, available as an All Terrain as  well as a regular Mud Terrain. This size of tyre is still 33" tall, just a little narrower than what you have.

There is also the 255/85R15 that is the same height. There's much less choice in this size, and they're all MTs. They are also really a bit narrow for your 10" wide rims. I run this size on a 16x7" rim. These sit nicely inside the wheel arch, so minimal mud or cyclists would be thrown up the side of your tidy looking truck :)

What looks like beadlocks are what is probably not legal.

Those wheels are effectively split rims. Yes they are beadlocks but the tyre is sat in exactly the same way it would be on a normal rim. The beadlock is a flange in place of the wheel bead. Whilst they won't be e marked they are not beadlocks in the normal sense. 20190704_164533.thumb.jpg.0d18f3bc16a90b28993a870415dedfd7.jpg

The yellow is the outer rim as per normal wheels.

Sure.  That is a beadlock. Many beadlocks properly center the bead.  That does not make them legal. If you think you are getting pulled over for the tyres, you are just as likely to get pulled over for those.
