whats the aspect ratio? i agree anyway with mono (even if i'm a bit confused with some tire terms) because if you get tires not as close to the original then you would have a hard time reading the speedo or change the speedo cable overall just to get a good reading.

hi mono, i've just checked my old surviving suzuki sk410/ super carry manual, and it reads that the original carry size is 155R12C-6PR.

now the problem is i dont know how could i convert it in the tire size calculator. what i did was i inputed this: 155/60/R12, and is this correct? hopefully it is, because the best fit tire (with 15in rims) is: 215/25/R15, and it says: it's 0.5% too fast as compared to the original tire.

if this would be correct i would be gladly be shopping here for new rims. thanks in advance bro.

The aspect ratio is the ratio of the tyres width. So if you have a 155 80 12 tyre the width is 155mm the side wall is 80% of the width. The original size is 155 80 12 the C 6pr stands for commercial 6 ply. The correct size to go to for if you are wanting to change to 14 inch rims is 165 60 14. if you want 15 inch you would have to use a 195 45 15 tyre. If you want 15 inch rims or 14 inch with a different tyre size ie 185 55 14 i am pretty sure you will have to modify your bady work. Hope this helps. If you need anymore help feel free to ask.

15 inch alloys would be ok with 15x45.195 tyres i found some fitted on this site www.custom-vans-uk.co.uk

theres also ones with 17inch alloys fitted but looks like the arches have been modded hope this helps as im yet to find some for my van in most cases spacers and maybe extended nuts will be needed which spacers are available on ebay quite cheap

i have 14 inch rims with 185/55/14 tyres. 15 inch rims will fit if you can find some with the correct offset and PCD and I can tell you it will be hard and expensive. Took me over 6 weeks to find my wheels and i am in the motor trade. My tyres stick out from the arches by 1 inch so the wheel arches are having to be modified. You can put any size wheels on that you want depending on how much work/time/money you want to spend.

what is the correct offset for a super carry / bedford rascal ive looked all over the internet at pcd charts non of them mention the suzuki super carry at all? also do u know the centre bore size?

[monometalico]

Hello poison, I have been through this a few times on here but i notice you are a newbie so to save you searching through all the posts here is the info you will need. For a 6x14 rim you need a PCD 4x114, centre bore 60.1mm and the offset needs to be 15-18mm. Use 185/55/14 tyres. If you want 15 rims it depends on the width of rim you want as to what the offset would be but you can work that out from the back space measurement. Hope this helps you.

I had my suzuki every <aka scrum van> wheels replaced with 175/65/14 pcd100 (actually my rims have universal holes - can fit hubs for pcd114 & pcd100) and I had no problem in max turn. It's a freebie from a friend dealer of suzuki surlpus so I have to use it since my wheels are already worn-out. There were no modifications made when I used this new wheel set-up. Well, I feel it's a little bit heavier during initial run as compared with using my previous 12" set-up but noticed fuel economy on long distance highway trips.

I'll suggest not changing your wheel size to a bigger one if your cab is not equipt with power-steering features... it may give you more challenge during parking on crowded sites...

I had just came across this site ->Wheel Fitment Guide may help us during wheel sizing up...
