Tyre size

[Steve M Addicted PP Member Find all posts View Profile Close Steve M]

By running a set of 265/70/17 on the vehicle (up one size in profile) but having a 65 profile as a spare would this cause any issues if I got a flat, I was I informed with the Prado being a AWD the profile needs to be exact other wise damage would occur ? ... Cheers Steve

Steve in theory the diffs should take up any difference in diameter but I wouldn't risk it. On a previous constant 4wd vehicle I had some weird stuff happen when I replaced two tyres and left two pretty worn tyres on (could only get two tyres at the time and the next two were a week away). You can probably pick up a second hand legal 70 profile tyre as a spare and it doesn't have to match anything other than nominal size.

You will need to match the profile Steve, damage will occur if driving with 2 different profiles. Seen diffs destroyed by this.

Cheers Derek

Yeah I've ordered the at's in Bridgestone d697 A/T's In LT but in the factory 65 profile which will be in today but my wife is now asking why I didn't get the bf muddies like I was going to and put on the spare rims (steel ones I bought) I said cause I would have had to outlay another $315 for a spare due to higher profile, higher fuel usage and was thinking to myself do I really need muddies plus having to change over wheels when required. Then she was asking wether the at's will be ok for high country wouldn't the muddies be better for general off road plus beach/ sand etc ?? Bloody hell lol now she has me thinking again which way I should go. Told her we have done high country before with at's (bf's) and no issues. I can still get the muddies if needed tyre bloke said he would just send them back and get the bf muddies instead .... Cheers Steve

This has been discussed lots of times before and there really isn't a correct answer unless you are doing lots of off roading where muddies are a necessity. I have run BFG A/Ts for ever and a day and they were always good enough but I don't often play in mud. I was going to grab some steel wheels and put muddies on those. Still might but at the moment my $ are cut off something to do with spending too much. I still have to sort out what to do with the trailer wheels since I have 4 120 GX steelies and BFGs that won't fit the 150 at the pointy end and are illegal anyway (results in narrower track). Not a big deal for emergencies. I did manage to pick up some cheap Maxxis muddies for the Rodeo ($200 per tyre, which was probably the final straw camel thing with regards to $) which are good however they hum or scream on the highway as you hear the soft bits of rubber being torn off. Becasue the 150 is so quiet I think the noise would drive me crazy so the muddies are definately a play time tyre for me.

Given our driving these days is mostly road, followed by fire trail and then sand I have gone for an all terrain tyre on the 150 though Pirelli Scorpians as opposed to BFGs. Mainly because the guys who sell the BFGs offered me two Anzac biscuits for 5 unused Grandtreks and the Pirellis were less than $800 changeover. Pirellis seem good so far but only 10,000km on them so early days.

Steve, unless you are always playing in the mud/climbing High Country tracks, I would stick with the ATs rather than muddies. They are quieter, use less fuel, handle better on road which is probably where most of your km are done and are better in the wet. As you said you have already done the HC with no problems. I run BFGs ATs and have done so since about 1996 with no problems on trips all over Australia. PS I read somewhere in the last few days, and can't find it again, of a dyno test where they went up only one size of tyre but lost about 10% of power and torque because of the higher gearing. If you are in rough stuff all of the time that may be a fair compromise but if you aren't, it may not be worth it. Neil

Thanks Neil, had the D697 fitted up this arvo. There actually more aggressive then any of the pictures Ive looked at really happy with the look of them. Seems to ride really well and didn't notice any difference in firmness or anything. May be a tad noisier then the grandtreck which is to be expected. Havnt had it up to 110k but don't see any issues. I have always run the bf's but found them a bit skittish in the wet so thought I would try some thing different. Wether I've made the right choice or not time will tell ?? but as the wife said, bad luck if you havnt your not changing them till there bald lol......Cheers Steve

Thanks Neil, had the D697 fitted up this arvo.

I'm just curious as to what pressure were you advised to run them at Steve? I have the 265/60/R18 LT and was running them at 38 PSI but I've upped that to 40 PSI after consulting Bridgestone.

Congrats Steve, i'm sure you will be happy with your purchase, just keep your puncture repair kit with you when on the rough stuff. I have to say it is a lot less hassle having a tyre that will fit both purposes, like if you're around a national park or state forest one day and want to have a play, you don't need to go home and swap them out. I went the other way (having a second set of rims with muddies), i just purchased a set of Prado alloys, at the right price, for my Toyo Open Country MT's, 265 70 17's, probably one of the quietest muddies I have heard (have had Cooper STT's and BFG's previously). Well made and rarely require balance weights, good tread ware, highly puncture proof and stiff side walls (I read somewhere they can be run flat). Here is a write up i did on my last vehicle http://www.lcool.org/forum/viewtopic...o+open+country.

Cheers

Hi there fido, they said 36 to 38 all round. I use to run 40 in the old BF's and also the grandtrecks...........Cheers Steve

Mud tyres are for mud(thats why they're called muddies!). No good in sand, they just dig bigger holes! As most people have said here, ATs are a much better all round tyre(all terrain). Really don't know why people can't understand this?

Hi there fido, they said 36 to 38 all round.

You have put on 265/65/R17 LTs right? What's the load index and speed rating marked on the side of the tyre? It will be a number like 118H.

[Steve M Addicted PP Member Find all posts View Profile Close Steve M]

I understand what muddies are for and there are heaps of people including on here (PP) who run muddies even on sand with no issues. My main thought for the muddies was better traction off road on steep stuff and would have been on the steel rims I bought for that purpose only and keep the grand treks for around town on the alloys. But in the end decided on the A/T's which I've had on my 4 previous 4wd's.... Cheers Steve

Ahh Steve you're too scared of a change!! I used to have D694's on my previous 4wd and they were terrible in muddy conditions, but apart from that, AT's are good in most cases, high country included. Important thing is that you have LT tyres, as they're stronger/safer on rocks.

PS - There's a trip next weekend if you'd like to put the new tyres to the test

[Steve M Addicted PP Member Find all posts View Profile Close Steve M]

Yeah Glen I'm wary of changing things lol like my food, I'm not adventuress because I'd be pissed off if I ordered some thing different to eat cost me a fortune and it tasted like crap lol.. These certainly are chunkier then the bf at's I've had 3 times before and yes there definately an A/T which I double checked. Havnt checked out fido's question yet will do that soon. Sorry mate I saw that trip posted but I have driver training on the same weekend unfortunately and I still need to gety sliders of AJ when I save some more coin up. Wife just bought new leather lounge so empty bank account again lol..... Cheers Steve
