Neo Posted August 23, 2020 Report Share Posted August 23, 2020 Hi guys. Gir a 2016 journey r/t here. I’m due for new tires and wanted to try something a hit bigger. My stock is a 225 55 r19 and wanted to try a 245 55 r19 tire. Would i mess up too much with the speedo? Quote Link to comment Share on other sites More sharing options...
2late4u Posted August 24, 2020 Report Share Posted August 24, 2020 at 70 mph (112.65 km/h) 72.11 mph (116.05 km/h) ...................you will be off 2.11 faster than what your speedo shows i run 235 55 19 great selection of tires and better prices than the oem size and speedo will only be off 1 mph have been using this size on my 2014 with no problem,,,you can google tire size comparisons and it will give you all the info you need Quote Link to comment Share on other sites More sharing options...
KnightRoller Posted December 2, 2020 Report Share Posted December 2, 2020 BigWheels.Net has a tires page where you can plug in any size and it will give you width and height in mm. You can also plug in make/model/year and get a list of recommended sizes for what ever wheel you're running. I use this site a lot for reference. Wheel-Size.com is another excellent site that will give you Plus One and Plus Two sizes. Any height difference will always affect speedo readout to a small degree but typically not enough to be concerned over. Quote Link to comment Share on other sites More sharing options...
volkner10 Posted May 21, 2021 Report Share Posted May 21, 2021 Thanks for these insights. I want to replace my current wheels and tires with something bigger. I've already decided to have a set of KMC wheels but haven't figure out the right tires to install with it. Quote Link to comment Share on other sites More sharing options...
2late4u Posted May 21, 2021 Report Share Posted May 21, 2021 255 50 19 will be the biggest without rubbing from what has been reported on here,,, also your speedo will be accurate as well the same as your 225 55 19 Quote Link to comment Share on other sites More sharing options...
