Firstly, can people please put up their real names and competition experience or intention so that this can be used as real feed back to assertain what people want?
Also if there are other guys not on here that you know, then their opinion need to be recorded so post it under your alias but with their name to the coments.
All comments are relevant and the more the better. I'll total up the votes. There are probably more than 2 options so say what you think are why. There are no wrong opinions.
Obviously, this is more targeted at 4x4 Challenges rules and so more to the NI competitions.
For everyone's information the rule is currently 36.5" ie 927mm. My thought is increase to 37" ie 939mm.
Below are some of my thoughts that wee posted on the other thread.

To answer the tyre size question is very simple. In the 35" range there are no viable alternatives to either Simex or Silverstone. It is a rare size that is not well supported by manufacturers. If you want to encourage people to do something different then you need to include the tyre size that has alot of options. 37x12.5 is that size. There are some very good new types of tyres in this size. To allow them to be used and get a greater variety into the sport we need to allow the wheels ruts to be made 6mm deeper. Now as has been said many many times, a Hilux on 33's has the same diff clearance as a Patrol on 35's so a Hilux on 35's will make ruts as big as a Patrol on 37's. The big rut agument is a load of crap (in my opinion). If the size allowed it I would probably get a set of the new Maxxis Trepadors Competition that are only available in 37x12.5 (or 40's). It looks like a viable option to the ET. Isn't it boring having everyone using the same tyres? Oz was like that and then they opened the rule up and now they have a huge variety on tyres. Yes our terrain is different so therefore our tyre requirements are different. BUT within reason shouldn't we encourage diversity?
Also if you want to fit bigger brakes for SAFTEY, it means 17" wheels and there is no tyre on the market in 17" that is a viable option to an ET.

my 2 cents worth, if it is to be 37,s make a ruling a.s.a.p so i can get the stuff i need.
this idea of hilux with 37,s have an advantage is rubbish, true they might have clearence advantages, but how many safari's are slicing an inch off the bottom of their diffs and how many hilux trucks have now got safari diffs???, no one forces anyone to buy anything.
with the way competitions are going high speed is more of a factor, therefore the mud type pattern will become more popular, as my truck is light i do not see the need to run the simex and 37's offer more variety and in 17's this allows more room for bigger brake.
if these rules come in will they be used for the event in oct/nov? getting 37 inch beadlocks will be quite costly as i suppose they only come in alloy.
either way i dont care, i would just like to know a.s.a.p

Hi Darin I personally would like to see the tyre limit stay the same as it is at present,i know what your saying about tyre choice under the present rules but there is always the Simex 36" and
Super swampers,Where will it end ? in a year or two we will be having the same discussion bcause everyone will be using the largest tyre available,As far as Austraila goes who cares,why should we change any of our rules to accommodate them if they want to come over let them comply to our rules.

Me personally am still tryin to decide if 35s are just to big for my hilux driveline and having seen how well my old girl goes with 33s I may just stick to that after all nigel reed seems to do consistently well

Thanks for the replies guys. All I'm doing is trying to get a gauge of what people think. I f the demand is there I'll put a proposal together and use any feedback to back it up. As for rules changes, nothing can happen untill next year, if anything is to happen.
