  • Rear tyre size

    I have a 180/55 on the rear of my gsxr at the moment, and I need new tyres. Should I go to a 190 on the rear? What difference will it make?
    What size would i go, 190/50?

    Not necessary, stick with a decent sticky 180

      If you change to a 190 it'll make your bike less nimble.
      I would'nt bother.

        nah leave tyre size stock

        if you want traction think about running a set of DOT's like the bridgestone BT003

          I put a 190 on and didn't notice any difference. It will give you more tyre contact with the road through corners.

            it depends on your mass and the suspension setup you have
            have a look through the manual that came with your bike. look for the R22 table

                DOT is Department Of Transport approved for road use.

                If you use a 190 you will turn in slower and it will run out of front tyre before rear when really cranked over, this means you lose the front before the back starts to slide. I would prefer to lose the back first.

                  If this is the case, why do the guys racing use 190's. ?

                    When the eastern staters came over a few of them had 190's fitted, but from experience with a few riders they have found that the front starts sliding earlier when using the 190.

                    Check out the wear patterns on the bikes fitted with the different tyres.

                      isnt the front tyre on the 600s and the 750's the same as on a 1000?

                        yeah, 120/70R17 is pretty universal on the front these days

                            It really depends on the tyre design and the rim width, not sure about the GSXR but a few people have put 190's on the rear of their BB's (stock is 180 and a 5.5" rim) and it actually makes the bike turn slower AND reduces the contact patch due to trying to fit the tyre on the smaller rim Might be OK for drag racing but not cornering

                              Racing tyres also may have a different profile to road tyres - for example I think most road going 190s are 190/50 while the dunlops I used on the track were 190/55... not sure about the bridgestones, don't pay that much attention.
