Rodrigo Salfer Posted August 7, 2022 Share Posted August 7, 2022 Tire change in Begode Master Here in Brazil the original size 80/90-14 is not available. I can choose between 90/90-14 or 80/100-14 I would prefer the 90/90 for being wider in 1cm and 1,7cm taller and have less train track, but I don't know if it well fit. The 80/100-14 it is 1,5 taller and is the same wide Can you help me with pro and cons of these options? 1 Quote Link to comment Share on other sites More sharing options...
mrelwood Posted August 8, 2022 Share Posted August 8, 2022 The tire sizes vary wildly from model to model. Sounds like you are perhaps comparing different tire models? Btw, wider tires tend to have more train tracking than narrower ones, not less. Although 10mm is small enough to be drowned by the tire model differences.

Popular Post Raptor Posted August 30, 2022 Popular Post Share Posted August 30, 2022 (edited) , I just ordered for my Master (narrow rim) tire Heidenau K66 90/90 14 52P RF . It fit very precisely. A little bigger would not have fit ! I am currently testing with different pressures and running in the tire. I am currently testing with different pressures and running in the tire. At the moment, everything is working perfectly. I will write more about the results after some time.

Raptor Posted September 9, 2022 Share Posted September 9, 2022 (edited) 10 hours ago, Francisconyc said: Riding results? I did test drives with several different pressures. 50psi (3.5bar) - 26psi (1.8bar) . The most comfortable and well controlled is 27.6psi (1.9bar) with my weight of 236lbs (107kg) . Since this tire is now almost 21 inches, the pressure can be kept lower . If the pressure is more than 28psi it tends to bounce and vibrate on the gravel road and becomes like a regular tire. With lower pressure it is good even at high speed and at low speed it turns easily and is sensitive to control. Longer tests are still ahead. I will write when I have really driven the tire. Sorry!

The tire itself: Heidenau K66 90/90 14 I've recently installed the same tire, the same size 90/90-14 but since it is very precise i preferred to install spacers between batteries ans frame so to gain some space between tire and batteries. 4mm each side. At the first ride I felt like the first time I were riding an ECU, and after 100km I can confirm my complete disappoint, I can't ride over 40km/h without feel in danger, over this speed my Master start wobbling spontaneously and I can consider 40km/h the very last safe speed, a complete disaster IMHO. My weight is 65kg, I've stared with 30PSI, then decreased to 22PSI but without a noticeable increase in stability. I'll wait for another kind of tire and then I'll drop this k66 in the trash.

Although, first you might want to make sure that the tire runs straight. EUC rims don’t usually force the tire into place, so the centering must be done manually.
