For some measurements and calculations visit post nos 554 and 560 on pages 37 and 38 respectively.

Thanks. Looking at the snap and description in post 554 I have a suspicion that he measured backspace not offset. Now I wonder if he got the inside/outside wrong in post 560 as well ...?

When measuring backspace the inner side needs to be placed upside, and it looks that that's what was done.

Can the folks double check that?

I bought my wheels based on these measurements only.

Now that the stock wheels have 100MM backspace and stock tyre size is 205/70R15, and you will be using 215/75R15 with CFLs which are wider than stock leafs, so reduce the backspacing about 15mm on account of broad CFLs and another 10-15mm on account of tyres with bigger diameter. Now you need wheels that have backspace of 75mm or lower.

Hope this helps.

Edt: Whats your clearance from inner wheel to leaf at full right steering lock currently?

I suggest you go for 15X7J wheel in such an offset, that the backspace of the wheel is about 75mm. Just check the backspacing on a 15X7J with -20 offset, I think it will fit your need perfectly.

After reading on this thread and elsewhere on the net, it looked like Gypsy rims, with its 139.7 mm PCD 5 bolt pattern was the correct match for the mm540, albeit with a Negative offset(thereby pushing the tyres away from the leaf springs).
Since I was looking for a low-cost alternative, the Gypsy rims were the most appealing. Hence I bought a set of 5 rims at Rs 1190/- each. I got the rims yesterday, and i ran some quick measurements to try and gauge the offset.

Here are some pics:

Measuring the PCD plate from the inner part of the rim:
Attachment 143361

From the above, it seems to me,from a pure common-sense perspective, that the Offset seems to be Positive, which means that the tyres will be pushed towards the inside of the vehicle, i.e towards the leaf springs. Comments please.

Thanks, hope this helps.

Here are my calculations -

5.5J rims from bead to bead make 6.5" from flange lip to lip. Centerline would be 6.5/2 or 3.25". A +10mm offset would make 3.25+0.39=3.64" or 92.45mm of backspace. Not the exact 100mm of backspace as show in in the pic 143361 above.

The backspace would have to be 3.93" (7.55mm more) to make that 100mm or 10cm seen in pic. 3.25" center line with a (0.69" or ) +17.75mm offset would make 100mm of backspace as seen in pic.

Maybe the measuring points for mount pad and assumption of +1 inch for flange lip is incorrect?

Needed help for procuring Apollo Bullet, MRF Sand grip tyres in Hyderabad. If someone has any information, and the current price estimate, please let me know. I'll be really grateful.

AFAIK the current market price is around 6.5K per tyre for Apollo bullets & MRF sang grips.

as they are not in to production now.:Frustrati

but a different company is producing them & they are available at cheaper rates.

ATF Farm King Tyres

if there is no dealer of ATF tyres in Hyderabad then pune dealer can send it there.

i bought them @ 4.5K for a set of tyre+tube+transportation. (22,500/- for set of 5)

only transportation cost will be added for Hyderabad so IMO it will cost 4.6K in Hyderabad.

if you want send me a PM with your contact details & i will forward it to the PUNE dealer.

rgds,

Thanks anyway.

1.) Anybody know for sure if in fact BFG all terrain are no longer sold in India?

2.) Are there any tyre shops in India you would trust to order on line or over the phone, giving credit card info etc. and trusting them to ship them to you?

@Dirty Dan i tried for a full month and came accross only one answer that due to some BIS norms or some other norms that tyre which has not got isi number cant be sold in india legally but they will be back in 6 months time according to most sellers, as demand is high but ofcourse there will be some price increase
