Thread: Series rims on a defender?

I checked and you are right, a 235/85 needs to be fitted on a minimum of a 6 inch wide rim. Seems that I was previously misinformed.

Some side wall 'bagging' (and increased possibility of side wall staking) will be experienced (even at normal road pressures) when fitting 235x85x16 tyres to the minimum acceptable 6 inch rims - better when fitted to 7 inch rims.

That depends on the specs set out by the tyre manufacturer. Some will say min 6" rim required, some will specify different. Cooper for example specify the min rim width for 235/85 being 5.50", so their tyres are quite legal for standard Defender rims.

Interesrting, I was using the specs on the BFG website

currently in the defence force all 1/2 trailer rims need to have trailer use only painted on them, i believe it because the rims fitted are from series vehicals, from memory all rims fitted to 110's had to be checked and non 110 rims had to be removed and marked trailer use only.

there are also two different offsets on the trailers which the truckies never take notice of as they are always putting two different offset rims on the trailers. gotta love those little red stickers

2/2a SWB=239601= 5.0 inch wide, 2/2a LWB=272309= 5.5 inch wide, the Series 3 had a pressed ring joining the stud holes, they also had a larger size wheel stud, it was also longer, the Australian ROH wheel for the later series vehicles was AYG-8108 and was 6.0 inch wide

JD was correct the above information is not accurate, there are lots of different Series rims and some are UK manufactured and others Australian manufactured although often with the same part number.

However one question that has to be considered is that none of the series and early defender rims are designed for tubeless tyres. The ones for tubless tyres have a ridge running circumfrentially around the rim just inside where the bead sits. If you dont have the safety rims you should run tubes.

Now back the the Series rims. (The part number is usually stamped on flat between the wheel studs)

* the 1948 rims are 4 1/2" wide, no branding on the flats & valve stem hole in the slot.
* 231601 - 5" wide, '49 - series 3 88" rims 49-53 UK manuf. only 53 on UK & Aust manuf.
* 272309 - 5 1/2" wide, 28/16" offset, '58 - series 3 109" rims, 7.50 tyres, UK or Aust manuf.
* 569690 - 5 1/2" wide, 21/16" offset, series 2a - series 3 109" rims UK manuf. only, 7.50 tyres (often called English rims)
* 526753 - 15" rim for 8.20 - 9.00 tyres UK manuf. US market.
* 543384 - 6 1/2" wide, no offset UK manuf. SIIA Forward Control 9.00 tyres
* 569204 - 6 1/2" wide, 13/16 offset UK Manuf. One Ton Land Rover 9.00tyres
* 569203 - 6 1/2" wide, aprox 3/4" offset UK manuf. SIIB Forward Control 9.00 tyres
* NRC7578PM - 5 1/2" wide, Unknown offset, series 3/stage 1/County, UK and Aust Manuf. 7.50 tyres


Only the very late series 3/Stage 1 rims (AYG-8108) had the raised ring between the studs. Whether it was 6.0" I am unaware.

Hope this helps

IME it is better to fit tyres to the narrowest rim possible, as the rim is protected by the tyre.

I have seen 235s fitted to 5.5" wide LR rims many times without problems.

Well Diana, mine are 5.5 and my opinion, for what it's worth and from advice, 235/85 should (that's should) be fitted to a 6 inch rim at least.
