Same Tyre Size On Front & Rear of Bullet Electra Twinspark. Why?

[cooldrive]

I have filled Nitrogen in my tyres today, I haven't checked physically if there was lot of heat in the tyres after filling the Nitrogen. But I did felt a slight improvement in ride comfort & the bike felt more stable than I did before even when taking tight corners at a good speed (at about 40-50) I would say that's good improvement for me. However the ride quality & improvement depends on how much PSI you set as well, if its not even there could be some issue. Currently I put front 30 & back 35 PSI

You mean to say that you had filled nitrogen in your tube tyre, Nice friend this comes as a news for me, this is the first time hearing something of this kind. Tight corners on a Bull at 40-50 is good enough, keep updating so we can learn better.

My '98 Machismo was the only model in the RE rangealongwith the 500 CI that came with the 3.5x19 tyre at that time. RE had two OEMs for the same size - MRF and Dunlop. My Machismo came with a Dunlop that started developing cracks in the sidewall at 12000 km despite my treating the bike like a baby and ALWAYS parking it in the shade. The tyre lost its tread at 15000 and I replaced it with MRF 3.5 x19. Though I do not find any significant difference in the road grip, the MRF certainly feels more durable than the Dunlop. I think you will not get any other Indian tyre of size 3.5x19 as no other regular production motorcycle wears a 19 inch rim. So it is better to stick with the MRF. However, do check out websites of foreign manufacturers loke Pirelli and Avon - they might have something in store for you.

I will stick on to MRF and will look on Avon, have heard a lot about it. Will see if I can find it here in Chennai or Bangalore.

Hi Guys,

Sorry if this question doesnt make sense. but in Royal enfield official site, under tire comparisation between Electra 350 and classic 350, its like this

Classic : front tire : 90/90 - 19
Classic : rear tire : 110/90 - 18

Electra: front tire : 3.25 * 19
Electra rear tire : 3.25 * 19

Here if i say 3.50 * 19 (insted of 3.25 * 19), does this mean its 110/90 - 19 (of that of classic)?

basically i want to compare rear tire size of both classic and electra. Planning to book one of the both.

ALso Cooldrive, can you tell me about corner stability and braking of the bike after upgrading to 3.50*19

Nope! 3.50x19 is not same as 110/90x19.

Here width of Tyre is given in " Inches "
where as in 110/90, it is in milimeter.

1 inch.= 25.4mm

3.50 tyre is 88.9 millimeter wide where as 110/90 tyre is 110 milimeter wide, 90 indicate it's aspect ratio, it determines sidewall height, 90% of 110 = 99mm tall sidewell

So 110 section is much wider!





Let me tell you one more thing, if tyre size is given in inches with no aspect ratio available it probably means 100% aspect ratio.

3.50 means 3.50*25.4= 88.9 , well 90/100 is close.


You can go for 110/90-18 a.k.a 4.33/90 x 18 but may need rim upgrade
Hope it helps!
