I dont understand tyre sizes (landrover 101 fc)

[julianf]

And the speed rating is?

Im not sure if ive ever exceeded motorway speed limit in the 101.

What i do know is that ive gone fast enough in it to be too scared to look down at the speedo.

...so probably at least 55mph.

Thanks for the explanations.

Where should I go from here? I can get what I have on there currently as part worn MOD stock for about £250 a corner.

Or, very roughly, what sort of money do custom rims cost, in order to make use of more common tyres?

For those that don't know, the 101 is six stud, so no common alternative rims, apart from the previously mentioned unimog rims.

Thank you

You are in luck Julian, I have just checked in the wheelery and there is a set of five 101 15" rims. A bit scabby but they will clean up, they came in a pile of 101 oddsnsods I bought. PM me if you are interested.

now theres something you dont see every day.

I just love the fact that, no matter how odd, no matter how rare, no matter when,

Usually @8ob will find something "floating" around!
Either he has a complete gold mine of random crap.
Or just warehouses full of stuff because he is a horder.

Either way,
I'm not saying it's a bad thing

 

[julianf]

315/75 r16 seem to be fairly "available"

75% of 315 is 236.75

That's not so far off the 100% of 255, which is what i have currently.


Am i missing something, or would that be an acceptable replacement?

Having driven one after lusting after one since I was a kid the phrase for me was never meet your hero’s(well not all of them)

In fairness if got significantly less fearful once i lost the bar grips. Next on the list is modern PAS.

@julianf 255 85 x 16's are available from the likes of Toyo, set of 4 new ones are about £500

Mathematically they work out at 33.7" so fairly close to your 34" target

Appreciate that the 101 is not the greatest of handling vehicles but there is less sidewall height if you stick with 16" rims

Again, I don't much understand this stuff, but wouldn't 315/75 r16 be preferable?

I'm not saying they are, I don't know, so that's why I'm asking!

Thank you.

You would need wider rims to accommodate a 315. I think the original 101 rims are 7"or8"
Edit: just checked and the original rim size is 6.5”, that will limit tyre size.

[Wildefalcon]

If that. I thought they were 6.5"

 

[indy4x]

@julianf if the rims are 6.5" then 255 85 x 16 will fit those rims

255 85 x 16 are will go on 6.5" to 8" wide rims

 

[Wildefalcon]

Yes, those Toyo tires will fit. The specification includes 6.5" rims.

I've just measured the Goodyear bar grips, and they are about 890mm, so the Toyo tyres are a little smaller at 850. The vehicle will be an inch lower.

The ride height is not so important as the circumference on something like the 101. It's probably revving plenty so unless it is lacking power and speed is not important, dropping by 20% will not be good on the road. What's it being used for? Off road not so important but that is a big jump from the bar grips.
138 mm difference per revolution -
890 = 2796mm circumference
846 = 2658mm circumference

My mate ordered a brand new set of 255/100r16 Michelins for his 101 through Costco. He has been down the route of old stock MOD stuff before and they don't seem to last but I think the biggest issue with most of these is they do not get enough use to keep flexing/moving the tyres.

It is a bit a pain, I fitted the previous set for him and even though they had the same sizes the one set were quite a bit taller. The original 900x16 bar grips were noticeably smaller.

I have another friend who has a RHD radio body 101, he got fed up with all the messing about so fitted some 110 axles, not something for the purist especially given how rare his is but it's his daily driver. He now has discs all round and axles where stuff like bearings are cheap as chips even for OEM. He now has a massive choice of rims/tyres available.

Will help with cornering.

I've not looked up the points, but mine has another engine already.

I'd really rather not loose the historic status.

That said, my front axle is needing attention also. The chrome on the balls is not good and they don't unbolt like other axels.

I've just looked. I hazily remember people on the lists talking about Costco a few years back but nothing is comming up for me now.

From the stuff I've read you can change stuff if original stuff isn't available or if the change is in the interests of safety or emissions.

All my made did was make leaf spring mounts for the 110 axles so going back to the original axles would easy.

I doubt anyone is ever going to be checking that kind of thing on a vehicle that does a few hundred miles a year.

My mate had to go in and have a chat with them, it took a while for them to get them in. It was in the last couple of years I think
