alfizta 6 Report post Posted April 4, 2014 maybe I'll try it to improve her looks. now she is with the originals 185mm thread tyres. I know it will increase wheel diameter, but I think it's just enough to correct the 2-3% error I get on speedo. anyone tried? what's your feedback?

Gibot123 16 Report post Posted April 7, 2014 its the side profile that will change your speedo not the width 185/ 60 195/50 number the 50 and 60 that will determine tyre height and overall circumfrence that and wheel size. Quote Share this post Link to post Share on other sites
alfizta 6 Report post Posted April 7, 2014 did not made myself clear, sorry. I'm trying to switch 185/60 R14 tyres for 195/60 R14 ones. that will increase width as well as diameter. anyone tried? Quote Share this post Link to post Share on other sites

The only difference between the 2 sizes you have here is the tyre width the 185 and 195 is the tread/tyre width the 60 the same on both sizes you have put is the height of the side of the tyre the diameter will stay the same. Just wider Quote Share this post Link to post Share on other sites
alfizta 6 Report post Posted April 8, 2014 the "60" on 185/60 means 60% of tyre width will be tyre's height. that will be 0,60x185 = 111 mm. on a 195/60 would be 0,60x195=117mm since the alloy is the same, difference in diameter for the whole tyre would be 2x117-2x111 = 12mm overall diameter would be for the 185/60 R14 2x111 + rim diameter = 222mm + 14inchx25,4mm = 577,6mm for the 195/60 R14 2x117 + 14x25,4 = 589,6mm 12mm difference as well Quote Share this post Link to post Share on other sites
Gibot123 16 Report post Posted April 8, 2014 they will fit but thought that the 60 related to the tyre hight not a percentage of width Whats the weather like in PORTUGAL Quote Share this post Link to post Share on other sites
