Sadly, my wonderful electra cruiser got stolen on tuesday. I am a college student with no other transportation, i need a new bike RIGHT away, the busses in my town are currently on strike and not running, so im looking for a cruiser around 120$. Im 5'7 300 pounds (yikes!)
Before, i kept getting 4 flats a week. I already determined the cause in my previous question, it was that, in short, i need a higher air pressure. The tires i had (that were stolen with the bike) were 26 x 2.125 and read on the side wall that they can hold 45-65 PSI of air.
Walmart has cheap cruisers. So today i went to walmart and saw:
Most cruisers there had 26 x 1.25 tires, much thinner than mine. Only a few had 26 x 2.125..... (Which is what i thought was standard for cruisers)
They all said on the sidewall the "tire can only hold 40 PSI of air"
Why is it that, a tire the exact same size as mine, would hold much less air than mine? And if i bought one and kept the air at 40 psi as it says, wouldnt it feel just like my old bike did at 40 psi (harder to ride, meaning more difficult to pedal) and have the flat issue all over again?? Huffy cruisers usually match the tires to the bike... So it would not be ideal to simply buy new tires.
There is another bike on craigslist im looking at. Its a genesis cruiser, big bike, with 29" tires. The reviews all say its ideal for bigger people... However yet again, the tires are only 1.25" wide... (I thought heavier people need wider tires?) And again, they only hold 40 psi of air (Ugh!)
In conclusion, i am asking the following:
- Why would the same size tire have different air limitations?
(The bike(s) im looking to buy, the tires say "fill tire to 40 psi" when normally, it would say "40 PSI - 65 PSI". All the tires say this no matter the size)
since tires usually say "40-60 psi" rather than just one number, could these tires say just one number (40 psi) because thats a good median, meaning i could get away with 50-60 psi?
If i can not afford new tires in addition to a nee bike, would you reccomend i stay away from these bikes with tires that can only hold 40 psi?
Say i were to purchase the genesis, which has 29"x1.25" tires that say they can only hold 40 PSI.
I heard bigger people need wider tires (like 2.1" and up) and more air pressure. Would the fact that these are bigger, 29" tires make up for the fact that they are thinner and hold less air in terms of an easy ride?
Could i change the 29" x 1.25 tires for 29" 2.125 tires with out changin the rims?
Any suggestions for where i can purchase an inexpensive beach cruiser style bike that doesnt have this tire issue?
