I am getting different options , can you tell me the fattest front and rear tires i can put on my 2017 Sportster 883 iron without a conversion kit please ???

Peter

 

AFAIK 160, though they told me if you remove the belt guard you can manage a 170 or a 180. If you want a 200 you have to go for a chain modification.

 

180 will be big enough ,,,,thanks now to decide which tires i'm liking Coker but a bit expensive,

 

just to confrin ,,, that would be 180/80 15 ?

 

The rear tire on the Iron is 16 not 15, and its the same for rear of both the 48 and Custom.
TIRES, REAR SPECIFICATION 150/80B16 77H
TIRES, FRONT SPECIFICATION 100/90B19 57H

The difference is the forward tire with Iron having a 19 inc vs the 16 of the 48 and Custom.

 

Peter, let's go back to basics for a few moments! There are several things that limit the size of tyre we can fit, the first of which is rim width (diameter goes without saying!). The rims on your bike, depending to a small degree by brand, will limit how wide a tyre you can fit. I doubt very much if there is any 180 wide tyre suitable for your stock 3" wide rim.

Other considerations are clearance with other parts of your bike, especially with your drive belt and belt guard. You can measure your current tyre's width, also see and measure how much clearance you currently have with the guard etc.

A further consideration is that as tyre width is increased, profile/section is reduced and rim width also increases. So while for example Avon supply a 160 wide tyre to fit your stock 3" rim, a 180 requires a 4.5" minimum width. Up front your 100 is as wide as it gets on your stock rim. The industry makes a limited range of tyres and not many bikes have 19" rims.

 

so i am trying to head towards the Harley Davidson 883 iron guerilla style.

 

At the least you'll need a replacement front wheel, as that bike has 16" wheels front and rear. Are you planning to ride that in the UK?! I've just read a tyre report in Ride magazine reviewing wet/cold weather tyres, because that is what we so often get here, whether we like it or not! And no front mudguard, nor much suspension?

 

i will be lucky enough to ride this only in good weather , so its all about the look for me ...............

 

You can easily mimic everything you see in that photo, except the front wheel. While there are plenty of brands of tyre to look out for, the size you currently have is your limit AFAIK, although you may find one that matches up to the rear in style. It may be possible to install a fat front wheel in your forks, but we'll have to rely on another expert to advise on that!

I do recommend removing those darned silly spikes in the footrests, if you haven't already. They will bite when passing with bare legs in the garage (a nasty wound in my case), they also reduce safe cornering clearance.
