I recently modified my dream machine the original pulsar150,by adding alloys and wide tyres both front and rear,so obviously the pick up will decrease,so i want to know that will there be any load on the engine,i drive slowly not crossing 60,or do i have to place light weight tyres to reduce the load on the engine,kindly suggest me as i love my pulsar,can i install K & N filter to increase the pick up

Technically yes you can, HOWEVER!! The 23x8's are taller, thinner tyres so they might affect your speedo reading and handling if they are not a standard Polaris size. The front end will also ride a tiny bit higher than the rear end. If you haven't got the original handbook try contacting Polaris directly or a dealer with your vehicles details and ask them what sizes are recommended for your ATV.
ATV tyre sizes translate as follows... a 23x8-10 tyre will be-
= 23 inches in diameter measured all the way across the widest part of the whole tyre.
= 8 inches across the width of the tread of the tyre.
= 10 inch diameter of the actual wheel rim.
22x11-10 is 22 inches tall, 11 inches wide on a 10 inch rim.
23x8-10 is 23 inches tall, 8 inches wide on a 10 inch rim.

could be a bent axel or your front end needs adjusting.

Doesn't sound right, unless wheel is damaged bent/cracked. A cheap fix would be "fix a flat" (sealer in a can) in each tire just as a safety precaution. Also check your tire valves sometimes tire shops don't get the valve cores tight.

I really don't think you will be able to use those rims and tires, probably the biggest is going to be 18" wheels. The 8.5" rim is too wide. An 18" came as the stock size on the sport package for the Jag, it's 7.5 wide. I don't think who sold them to you really knew if they would fit or not. Without wheel spaces and raising the suspension, I don't think they'll work on the car.

150 section. might get a 180 section with standard rear swing arm or 240 with modified swing arm shock mounts and extended drive sprocket and cover. do a search on wide tyre(tire) kit for harley.

Front tyre 3.50 - 18
Rear tyre 4.00 - 18
You'll need tubes too.

what design are they, two thing could be doing it, if the obviouse touching has already been investigated, one is the design, if the spokes/hub sits out further than the rim than the outer of the rim they could be catching the wind and making some freaky noises, or if the center dishes in then maybe they are "loud" tyres by that i mean do the tyres have wide grooves, directional etc, high performance tyres are in principle very noisy. hope this has been handy.

Hi!
You are asking a sensible question and obviously are concerned and rightly so for your safety and others plus tyre wea.
Good on you!
However it depends on load,circumstances, conditions and the type of tyres/compound you have.
So as a rule of thumb, 28/30 front normal conditions rider only short journeys, 30/32 rear normal 2 riders +- 2psi for loads and long runs.

The Cali' Special tyre pressures:- --------------- 1 RIDER.---------------------- 2 RIDERS Front ...... 2.3 Bar(33.5psi) ................... 2.3Bar(33.5psi) Rear ....... 2.5Bar(36.3psi) .................... 2.9Bar(42psi) I use BT45's on mine but I have the ordinary tubed rims. I find the ride harsh but this may be down to suspension rather than tyres. People recommend running the BT45 at a slightly higher pressure than the book. I got 8500 miles from the front and 4700 from the rear. Although the rear was changed slightly early due to a puncture. I will probably try a different make next time.
