tyre sizes

Hi, i am planing on putting 14inch wheels on my 95 super carry. 185/55/14 tyres are the same rolling circumference give or take 6-8 mm. The problem i am having is finding some wheels with the correct PCD and offset. Plus i may have to add some width to the wheels arches as these tyre will have to go on a 5 1/2inch rim.

sir if i may ask to have those pics posted so i could do it to my carry too. thanks!

 

I have just moved house so am busy sorting out my workshop. As soon as i get started on the van i will post some pics of the progress. I am still trying to source some 14inch rims to fit but i have a lead to follow up on tomorrow. will keep you updated.

 

related to tire size, i noticed some carry have their wheel wells rounded in front unlike some which have like an arc starting from the front then abruptly goes in a straight cut at a 45degree angle down. do we need to trim this and make the wheel well rounder to accomodate bigger tires? is size 15 rims with low profile tires going too far?

 

the problem is not in the arches bro. its in the "tire well" or the allotted room suzuki manufacturers made for the front tire to play when turning full left or full right. definitely it will not carry wide and tall tires, only size 13 is able to play within the front. i wonder if size 14 fits in the rear part of the van...

 

I am a motor mechanic and tyre fitter. I have no problem with cutting and rewelding wheel arches and as my van has a spot of tin worm. Plus i enjoy the challenge of the plans i have for my carry. There is a way of finding tyre sizes to fit your vans try using this tyre size calculator.

Tire size calculator

for example if you have 155/80/12 it works out pretty much the same as a 165/60/14

I will be using 185/55/14 if i can find the wheels to fit. I am having a hard time finding them.

 

Check one of the thread here that shows the pimp my ride first episode where they transform a Daihatsu Van.

You can watch the whole show and they even put a size 17 tire on that van.

bro i'm having a hard time using the tire calculator. could you help me use it? - i'm trying to check whats the max tire size from our stock tires.

 

mono hit it right on the dot! so mono, are you saying we only need to be concerned with the total diameter of our tires so as not to scrape the sheet metal when we bottom our struts?

i guess for really wide tires, we need a rim that's really offset far out to accomodate the tires. will steering be a problem with a 195 or 205?

another thing is i get a warning beeper when i my speedo reads 90khp. can we cheat this beeper with tire size. so that we're actually running 120 while it still reads 85kph? do you guys have this beeping sound too?

 

the pic is a bit blurry but i took this one with my celfone just this morning, a Carry pickup with giant tires

 

that's one humongous tire!!!

 

yup, must affect the drivetrain bigtime too

 

kung hindi pinalitan ang tranny or gear ratio's nito, I bet madali lang mapudpud a clutch disc nito. You have to sacrifice the clutch disc para lang umusad ang sasakyan... esp kung may sakay....

 

yup yup yup! eto pa bro: just found also a carry pickup na pinalitan ang tire rod to accomodate bigger tires when turning, parang r15 or r16 ang tires ata eh.

 

okey dokey J-six and isporttrax i will try see if i can help you guys out. Right if you go to the tyre calculator and put 155/80/12 in the stock tyre box then put for example 165/60/14 in the new tyre box the info it gives you is-

155/80/12- 165/60/14
sidewall- 4.9inch - 3.9inch
radius- 10.9inch - 10.9inch
diameter- 21.8inch - 21.8inch
circumf- 68.4inch- 68.5inch
revs per min- 927.0- 925.0

it also tells you that your speedo will be 0.1% slow, so if your speedo reads 60mph you are really doing 60.1mph. So you can see there is no problem fitting the 165/60/14. if you wanted to go to 15inch wheels I would say that 185/45/15 tyres would be the size to go for. I do not know how the fit would be as far as fouling the body work when stearing but as i have said before that is not a problem for me as i am going to modify the body to fit the wheels. The law says that here in England wheels can not stick out from the wheel arches i dont know the laws you have to work to. As soon as i can i will update you guys with my progress and will post some pics as soon as i can.

ps i am still having major problems finding wheels to fit my van.

Regards to you all

 

good luck mono on your wheel fitting adventure! its hard to find wheels with ous pcd as most modern wheels wont fit. we dont have same rules here in the phils so its ok for our tires to stick out. its all a matter of preference. my only concern is the mud and dirt squeezing under the door as i dont have extended fenders so i have to watch out when i get off the truck so as not to get my pants dirty.
thanks!

 

yup we do have the same rules but as compared in england the law enforcement could be dealt away with bribing or escaping the cops.

thanks sir mono.i wish i could do body remodelling to the van too just so to accomodate big tires. thanks for the sizes of the tires sir!

 

Hey isporttrak, its not the PCD or offset that is the problem for me finding wheels its the centre bore size. Its starting to look like i am going to have to buy some wheels with the correct pcd and offset then get the centre bore machined out to the correct size.

 

oh i see. encoutered the same issue way back. hope you get a good shop who'll machine it for you! pls keep us posted on developments on your end. would appreciate pics!

 

Spoke to my wheel supplier today he has come up with 3 different wheel types that he thinks will fit, He has even suggested that he may be able to get me some 15inch rims. Will be going with 15 if he can get them. I will post pics as soon as i can.

 

Good day monometalico,
Just curious about this topic on changing to bigger tires.
In your experience as motor mechanic and tire fitter, any advantage
of having a bigger (over-all diameter) tires compared to just the original
ones provided by the company who designed it.

Looking forward to your reply.

Thanks.

 

hi mono,

no need to machine your new wheels if you can find aftermarket wheels which come with hubcentric rings that lock into the back of the wheel to center it like a factory wheel, usually made of plastic or aluminum. some call it spacers. i used to have those on my mitsubishi mirage which i fitted with bridgestones 205/50/14 wheels. the tires said it all!

 

Hey BruceLi and isporttrax. I know what you mean over here we call them spigot rings but i am not a big fan of the plastic type. I have seen these on cars. Have seen it when the plastic type has not been put on correctly and has caused the wheel to work lose! if you are going to use these use alloy ones!

BruceLi sounds like a trick question. You ask about bigger diameter wheels and tyres. Remember that when you up size wheels and tyres you are remaining with a wheel tyre package that has the same rolling curcumference as the standard wheels and tyres. Dont be thinking that by fitting bigger wheels and tyres you will be gaining any perfomance benifits. Maybe if you had 250bhp you would need a bigger tyre for a better contact patch the help transfer the power. Bigger wheels on a super carry van are only for looks and nothing else. Hope this answers you question.

 

yup. in addition it will enhance the stock tyre look of the van. in the other forum, as i had said, the original tyres were small and puny, similar to my suzuki apv. that's why we had the tyres upgraded to fatter ones, 175/70/r13. the logic is that the puny tyres are meant to cary more load, but if you try replacing them with bigger ones at least you would have a sense of security that it will not topple over.

mono, isn't it its very dangerous if you move to r15 in a super carry especially moving very fast about bends?

question on spacers: will it help accomodate bigger tyres even on a super carry? i know i could only fit a max of r13 in it.

 

j-six, if you opt to get bigger rims, you should get lower profile tires. ideally we want to achieve the total diameter to be close to the original so as not to alter the speedo reading that much.

you can fit rims bigger than 13inch on your ride. use the tire size calculator to help you. the lower the difference in speedo reading to the original, the better. unless you're not so concerned with your speed but rather on the looks of your ride.
